- the maleimide-based particle comprises between 10 wt% and 70 wt% of the functional additive (s) : wt of the sum of the functional additive : total wt of the maleimide-based particles.
- Preferred substrates are selected from the group consisting of fabrics (e.g. textiles, non-woven fabrics; any textile or fabrics are suitable) , cellulosic material (paper, carton boards) , leather (natural or artificial) , wood, paints and concrete.
- a most preferred substrate is a surface, such as fabrics (a textile or a non-woven fabric; for instance wovens, knits, tufted, sticht bound, carpets,...) or synthetic leather.
- a fiber (cellulosic or to be used in fabrics) is also a possible surface.
- Preferred polymer formulations are selected from the group consisting of a solution, an emulsion, a dispersion or a solvent-free composition (e.g. of monomers and/or of oligomers) , more preferably, the polymer is in the aqueous phase.

- Figure 5 Dispersion of poly(styrene maleimide) -based particles : polymer according to a preferred aspect of the present invention.
- the inventors have found that it is possible to use the small particles based on a maleimide polymer to encapsulate functional additives in an amount sufficient to allow the additive to exert its desired function, even in the case of the additive, or of one of the additives, is a thermo-regulating agent.
- a polymer formulation (of a Tg between - 60°C and 100°C, preferably between -55° and 50°, more preferably between -50°C and 0°C) to the maleimide-based composition, despite of the dilutive effect caused by the polymer, that can be major, allows to more stably incorporate the maleimide particle on a substrate such as a surface and is even useful to narrow the temperature transition range to the desired temperature (e.g. corresponding to the temperature of the skin) .
- the choice of the polymer formulation allows to easily adapting the stiffness of the resulting composition, while the adaptation of its relative abundance with regard to the maleimide-based particle allows the optimization of the resulting properties.
- the present mixture which is stable and non- viscous, can be applied in different forms, such as a foam or a paste, that will in turn produce specific properties (e.g. breathability when applied as a foam vs air tight when applied as a paste) , depending on the needs .
- the inventors have chosen the challenging way to try to develop, for the textile industry, particles based on a poly(styrene maleimide) particles and not to select the well-established melamine-formaldehyde coating system. Indeed, a suspension of poly(styrene maleimide) particules, when dried, results into a gel full of cracks, then into a powder.
- a first aspect of the present invention is a process for treating a substrate comprising the steps of forming particles based on a maleimide containing polymer and comprising a functional additive, of obtaining an homogenous mixture, of adding this mixture on a substrate, and of allowing the mixture to dry or to cure.
- the process further comprises a step of mixing a polymer formulation to the particles based on a maleimide containing polymer and comprising a functional additive so as to form a second homogenous mixture; in this process, the drying or curing step allows the polymer to become a film on this substrate, for instance a film where the polymer forms a matrix where the maleimide containing particles are homogenously dispersed .
- the maleimide containing particles are small, with a mean diameter between (about) 100 nm (preferably about 200 nm) and (about) 1 ym (preferably less than 300 nm) .
- particles based on maleimide or “particles based on a maleimide polymer”, it is preferably meant a poly(styrene maleimide) copolymer stably charged with a functional additive.
- the “particles based on maleimide (or on a maleimide polymer) " may also be formed from other cyclic anhydride (for instance an unsaturated organic molecule with two carboxylic groups on one molecule, so as to form a cyclic anhydride, possibly with a molecular weight of less than 300 Da, possibly less than 200 Da) .
- cyclic anhydrides are co-polymersised with olefins such as styrene, ethylene, propylene, alpha-olefins .
- the cyclic anhydride is usually maleic anhydride, but can also be itaconic anhydride or substituted derivatives of maleic anhydride.
- the corresponding cyclic anhydride containing polymers are then reacted with an alkyl amine to form the corresponding reaction products: imides, amides and ammonium salts.
- the cyclic anhydride is for more than 50% transformed into the imide (e.g. between 50% and 95%, possibly between 60% and 90% or even between 60% and 80%) .
- the maleimide containing polymer will form a particle.
- non-water soluble or slightly water soluble products can be added. These products will be encapsulated during the transformation process.
- the resultant particles have usually a size smaller than 1 micrometer, mostly even smaller than 300 nm.
- the encapsulated additive can make up till 70% of the total weight of the combination encapsulant and encapsulated product.
- the maleimide coating particles Due to its small size the maleimide coating particles have multiple advantages compared to the melamine formaldehyde encapsulating systems.
- the small size provides a much higher stability in the aqueous phase, while having the possibility to keep the viscosity low.
- the maleimide containing particles are more homogeneously embedded in a resulting coating. Especially in thin coating layers the particles will not stick out of the coating surface.
- the maleimide containing particles When combined with polymeric binders the maleimide containing particles will more act as inert materials compared to melamine formaldehyde resins, meaning that the physical properties of the polymeric binders will more prevail. As such when adding low Tg polymeric binders the softness of the binder will be sensed better in combination with the maleimide containing particles than with melamine formaldehyde resins.
- Such maleimide containing particles especially the particles based on the poly(styrene maleimide) copolymer can behave as a sponge.
- the additive is stably incorporated (able to stay there for more than 1 month, preferably more than 2 months, even more preferably more than 1 year) in the matrix.
- the addition of the polymer formulation is beneficial for this aspect.
- thermo-regulators e.g. a specific wax
- flame retardant e.g. a specific wax
- biocides anti-microbial such as antifungal or antibacterial
- insecticide such as antimite, anti- mosquito, anti-acarid
- light absorbing and/or emitting compounds odorant, odor controlling agent, skin care agent, color pigment and probiotic material.
- several functional additives can be applied in one step of the process of the present invention, either because they are incorporated in one maleimide-based particle, or if several maleimide-based particles, comprising different functional additives, are mixed .
- the glass transition of a polymer is the temperature at which the morphology of the polymer changes from a hard and relatively brittle state into a rubber like state.
- the Tg can preferably be measured by differential scanning calorimetry where the material is heated at a rate of lOK/min and the heat capacity is recorded in function of the temperature. In other words, the Tg can be measured by plotting the heat capacity as a function of temperature, then the Tg temperature is derived from the intersection of two tangents (at the start of the endotherm and at the maximal variation) .
- the Tg temperature can then be defined as the middle (B) of the onset (A) and the end (C) of the increase in heat capacity (Fig. 1) .
- the Tg temperature of a polymer is fixed at a viscosity of 10 12 Pa-s.
- the polymer (or a mixture of polymer) usually have a Tg between -60°C and 100°C (preferably between -55° and 50°, more preferably between -50°C and 0°C) .
- Tg between -60°C and 100°C (preferably between -55° and 50°, more preferably between -50°C and 0°C) .
- the lowest Tg values being associated to softening effects, the highest Tg values being associated to a stiffening.
- Mixtures of polymers can be used in the polymer formulation, provided that the resulting Tg value (without taking into account the particles based on maleimide polymers) remains in the range as above.
- the Tg value of the poly(styrene maleimide) -based particle is much higher, in the range of 180°C, which allows process conditions at relatively high temperatures, provided that the functionalities of the additive (s) are preserved.
- Preferred polymers are selected from the group consisting of acrylics, polyurethanes , poly vinyl acetate, Polyamides (PA) , styrenebutadiene latex, natural or synthetic rubber, poly vinyl butyral, polyethylene, Ethylene Vinyl Acetate (EVA) , polyesters, natural latex, bio-based polymers (e.g. polymers and derivatives thereof from monomers from natural sources, such as poly- neoprenes, poly-isoprenes and polylactic acid) , and halogenate derivatives thereof.
- PA Polyamides
- EVA Ethylene Vinyl Acetate
- polyesters e.g. polymers and derivatives thereof from monomers from natural sources, such as poly- neoprenes, poly-isoprenes and polylactic acid
- bio-based polymers e.g. polymers and derivatives thereof from monomers from natural sources, such as poly- neoprenes, poly-isoprenes and polylactic acid
- bio-based polymers e
- this ratio can vary. It is preferably not below 1:100 and not higher than 100:1.
- Usual ratios are comprised between 1:10 and 10:1, preferably between 1:5 and 5:1, more preferably between 1:3 and 3:1 or close to 1:1.
- the ratio may be varied according to the needs; the important aspects is to avoid a too heavy dilution of the functional additive (thus not too low ratios, yet ratios below 1:1 have been found as acceptable, even in the case of incorporation of thermo-regulators on fabrics) and to allow the resulting mixture to still form a film comprising the particles (thus not too high) .
- the formulation of the polymer is a solution or a dispersion, such as an aqueous dispersion of a polymer .
- the polymer formulation can be a mixture comprising one or several monomers and/or oligomers (for instance to be polymerized at the curing step) , and this mixture can be solvent- free.
- the polymer formulation can be an emulsion or dispersion, which is advantageous if foams are to be produced.
- the drying step is chosen according to the standard practice. Drying is usually performed by heating. In this case, if a polymer formulation is present, the temperature should be fixed at a temperature higher than the Tg of the polymer (the Tg of the polymer molecule present in the polymer formulation) and lower than 220°C, preferably lower than 180°C (the Tg of the particles) .
- An usual temperature in the textile industry is of about 120°C. Relatively higher temperatures ranging from 180°C to 220°C can be fixed for heating steps not longer than 30 seconds. Heating can also be performed by irradiation (e.g. microwave, IR) .
- the drying step can also be done at room temperature.
- the polymerization is performed in situ, and, for instance, the heating step / curing step is achieved upon UV-irradiation .
- a process for treating a substrate (fabrics) where a formulation of a polymer is added to a poly(styrene maleimide) -based composition so as to obtain a homogenous mixture, this mixture being added to the substrate and being dried (preferably by heating) , wherein the formulation of the polymer is a solution, a dispersion or an emulsion, preferably an aqueous solution, an aqueous dispersion or an emulsion comprising an aqueous phase.
- Another related process is a process for treating a substrate (fabrics) where a formulation of a polymer is added to a poly(styrene maleimide) -composition so as to obtain a homogenous mixture, this mixture being added to the substrate and being cured (preferably upon UV exposure) , wherein the formulation of the polymer consists of one or several monomers and/or of oligomers that will subsequently undergo polymerization. Possibly the formulation of the polymer is solvent-free.
- a related aspect of the present invention is the substrate (fabrics) coated when carrying this process.
- the present invention further relates to substrate further comprising a film of a polymer comprising a (an homogenous) dispersion of particles of a poly(styrene maleimide) -composition comprising at least one additive (s).
- a knit with a mixture of poly(styrene maleimide) -based particles comprising a phase change material, such as a thermo-regulator (Ps/Tr) and poly(styrene maleimide) -based particles comprising a flame-retardant (Ps/Fr) and further comprising the polymer composition made of acrylic polymer (PA) (Ps/Tr : Ps/Fr : PA 3:2:1) .
- Ps/Tr thermo-regulator
- Ps/Fr poly(styrene maleimide) -based particles comprising a flame-retardant (Ps/Fr) and further comprising the polymer composition made of acrylic polymer (PA) (Ps/Tr : Ps/Fr : PA 3:2:1) .
- PA acrylic polymer
- the resulting woven remains breathable and soft and has acquired an intense "cool touch”.
- the mixture of the present invention e.g. made of poly(styrene maleimide) -based particles : polyurethane ; 1:1
- a foam such as PU/latex foam
- Another related composition is made of poly(styrene maleimide) -based particles further comprising one functional additive (for instance a thermo-regulator additive) and a polyol that is liquid at room- temperature.
- This composition further comprises a blowing agent (that can be water) and a cross-linking agent (e.g. isocyanate) .
- This composition is then cured to form a foam where the additive is embedded.
- Another related aspect of the present invention is a paste or, preferably, a foam comprising (or consisting (essentially) of) the composition of the present invention . Examples.
- thermo-regulators octadecane
- thermo- regulators octadecane
- an aqueous composition of an acrylic polymer with a Tg of -50°C so as to obtain an homogenous mixture.
- the inventors firstly selected a 1:1 ratio (dried powder : polymer) . The inventors then dried the homogenous mixture upon heating at 120°c for 2 min (i.e. a rapid evaporation) . The inventors obtained a film with good technical properties where the poly(styrene maleimide) coat is homogeneously dispersed. Then the inventors have measured the heat absorption in function of the temperature.
- the inventors have been able to displace the position of the peak, thus allowing flexibility to optimize the coating, depending on the end use of the substrate.
- stretchable fabrics tight fabrics, soft fabrics, stiff fabrics,...
- Example 3 Application of the coating according to the invention in a breathable textile
- the inventors then mixed the polymer composition as in Example 2 (in a 1:1 mass ratio) so as to obtain an homogenous mixture in the form of a foam.
- Example 2 Then the inventors have applied the foam to a textile at a high concentration on the back side of the substrate by foam application technique before the drying step as in Example 2.
- the inventors have noticed that the coating allows the air to pass through. As such, it is difficult to generate foams from melamine formaldehyde-based compositions.
- the maleimide-based capsules allow the insertion into an easy applicable coating formulation and to maintain nice foaming properties, which secures air permeability of the treated surface. Furthermore, at these very high concentrations, the color on the face of the substrate has not been affected and the "cool touch" effect is boosted by applying the encapsulated wax on one side of the fabric, meaning that the heat absorption capacity of the textile is better than in melamine-formaldehyde based compositions. This application remained stable on the textile for the time considered.
- the inventors have used the aqueous dispersion as in WO 2008/014903, further comprising a flame retardant and then mixed it with an aqueous composition of a polymer with low Tg ranges of -50 to -10°C (such as acrylic- or polyurethane-based polymers) so as to obtain an homogenous mixture in the form of a solution. Then the inventors have applied the solution to a textile by impregnating it at a high concentration in order to meet the specific flame retardant standards before the drying step as in Example 2.
- a polymer with low Tg ranges of -50 to -10°C such as acrylic- or polyurethane-based polymers
- the coating allows two features: a very good flame retardant effect due to the possibility to load much higher concentrations than melamin-formaldehyde alternative, even with taking into account the dilution due to the addition of the polymer, and the development of a wash-durable barrier due to the coating itself. Interestingly, the coating is wash durable and resistant to weather conditions.
- Example 5 Application of particles containing two additives
- the inventors have then encapsulated a thermal regulating wax in poly(styrene maleimide) particles, as well as flame retardant additives in poly(styrene maleimide) particles.
- These two types of particles have been mixed together with a polymer formulation ( PU : elastomer ; 1:1) and the mixture has then been applied on a textile substrate (e.g. a knit) by impregnation, and the substrate has been dried.
- the overall properties of the substrate including breathability, transparency, softness, elasticity, comfort, color and design have been kept.
- the two functionalities have been stably incorporated to the knit.
