Definitions
- the present invention relates to the field of polymeric materials, particularly in the field of polymeric materials consisting of macromolecular chains united by interactions of the hydrogen bonding type. It also relates to the processes for synthesizing these materials as well as their uses as additives in compositions.
- the materials of the invention can be used as such or for example as impact enhancing additives, rheology control agents.
- Another problem that the invention seeks to solve is the preparation of block or comb block copolymers by joining homopolymers prepared in a first step.
- the Applicant has found that these problems can be solved by the chemical modification of polymers by introducing therein a modifying agent comprising imidazolidone groups.
- the chemical modification of polymer systems according to the invention involves the formation of a covalent bond between the polymer backbone and the modifying agent.
- the modifying agent comprises, united in the same molecule, one or more associative groups capable of joining by hydrogen bonds and one or more reactive groups capable of forming covalent bonds with the polymer backbone.
- at least one of the associative groups of the modifying agent is an imidazolidone heterocycle.
- the polymer backbone considered may comprise a number of comonomers judiciously selected to facilitate the grafting operation, that is to say the attachment of the modifying agent on the polymer backbone by at least one covalent bond.
- the modified polymer chains are able to unite by cooperative hydrogen bonds, the role of associative groups can also be to reinforce this power of association if it already exists in the unmodified system.
- One advantage of this type of combination is that these hydrogen bonds are reversible: they can be broken by a rise in temperature or by the action of a selective solvent and then reformed.
- Associative groups can be introduced into the polymers by different routes. Mention may be made of copolymerization with a monomer bearing the associative group, use during the synthesis of the polymer of the modifying agent as a transfer or termination agent. According to the invention the associative groups are introduced on polymer or copolymer systems already formed by reaction with the modifying agent, in other words after the polymerization or polycondensation step. For polymer systems resulting from polycondensations such as, for example, polyesters and polyamides which de facto have reactive chain ends, the modifying agent may also be introduced during synthesis as a chain-limiting agent.
- modified polymers containing a greater or lesser number of associative groups can be obtained by varying the amount of modifying agent or the reaction time during the grafting step while to achieve the same result using monomers carrying the associative group, it is necessary to proceed in each case to a new polymerization.
- the object of the invention is therefore a polymeric material consisting of macromolecular chains linked by hydrogen bonds in which: the macromolecular chains consist of a polymer backbone on which is fixed by at least one covalent bond a modification agent, modification agent comprises, united in the same molecule, one or more associative groups capable of joining by hydrogen bonds and one or more reactive groups capable of forming covalent bonds with the polymer backbone, at least one of the associative groups of the modifying agent is an imidazolidone heterocycle, the macromolecular chains carry on average 1 to 10 imidazolidone groups per chain.
- the polymer backbone considered may comprise a number of comonomers judiciously selected to facilitate the grafting operation, that is to say the attachment of the modifying agent on the polymer backbone by at least one covalent bond.
- the average number of imidazolidone groups to be introduced into the macromolecular chains depends both on the average mass of these chains and on the final properties that are to be imparted to the material.
- a mixture of modifying agents can be used.
- different modifying agents may be attached to the same polymer backbone, a modifying agent may be attached to polymeric backbones and another modifying agent to the other polymeric backbones, the backbones may be mixtures of different polymeric backbones or any combination of these possibilities.
- the polymeric material of the invention can be extruded, coextruded injected, blown, molded, overmoulded, calendered, thermoformed. We can make objects such as for example tubes, films, plates, rushes, bottles, containers.
- the polymeric material of the invention may also be mixed with other materials such as other polymers, for example it is used as impact modifier or rheology regulator.
- the present invention also relates to the use of the preceding polymer material as a compatibilizing agent in a composition comprising among others at least two polymers belonging to different polymer classes.
- polymer backbones they may belong to different polymer classes. They are preferably chosen from polyolefins, polydienes, polyvinyls, polyacrylates, polymethacrylates, polyesters, polyamides, polyethers, polycarbonates, polysiloxanes, polyurethanes and copolymers of the above types. In a preferred form, the number-average molecular weight of the polymer backbones is between 1000 and 100,000.
- the modifying agent comprises, united in the same molecule, one or more associative groups A capable of joining by hydrogen bonds and one or more reactive groups R capable of forming covalent bonds with the polymer.
- the groups A and R are connected to each other by a rigid or flexible chain X:
- At least one of the associative groups of the modifying agent is an imidazolidone heterocycle.
- the reactive group (s) present in the modifying agent need not be a polymerizable chemical group but only a group capable of forming a covalent bond with reactive groups present on the polymer skeleton.
- R may be a halogen, an amino group primary or secondary, alcohol, thiol, aldehyde, ketone, carboxylic acid or derivative (acid chloride or bromide, acid anhydride or ester), sulfonic acid or derivative, isocyanate, epoxy.
- the rigid or flexible chain, X may be a hydrocarbon chain bearing one or more heteroelements, it may be a linear or branched alkyl chain composed of one to 30 carbon atoms, a ring or a ring. succession of alkyl or aryl elements united by bridges
- reaction of R with the polymer backbone may reveal additional associative hydrogen bonding groups and in particular amide bridges -C (O) NH- or -NHC (O) -.
- the modifying agent corresponds to one of the following molecules:
- Linear "multiblock” type association A and B different polymer backbones O: group containing the imidazolidone function. Different polymer backbones A and B carry a modifying agent at each of their ends. This results in a linear multiblock association, A / B.
- a and B two different polymer skeletons.
- O group containing the imidazolidone function
- a and B have different polymer backbones, each chain of A carries at least two modifiers and B carries a modifying agent at one of its ends or a modifying agent at each of its ends.
- the first fraction is not collected.
- the temperature at the top of the column is then 105 ° C.
- the mixing time is 5 min and gives the graft copolymer HT10-g-UD.
- the grafting is attested by the complete disappearance of the anhydride bands and the appearance of bands characteristic of the imidazolidone unit.
- the mixing time is 5 min and gives the graft copolymer HT121-g-UD.
- the grafting is attested by the complete disappearance of the anhydride bands and the appearance of bands characteristic of the imidazolidone unit.
- Tg (HTI 21) - 123 0 C and Tg (HTI 21 -g-UD) 129 ° C.
- the infrared LOTADER 3210 shows that a high proportion of maleic anhydrides is hydrolysed and will not participate in grafting.
- LOTADER 3210-g-UD a decrease in the intensity of the anhydride peaks is observed in favor of the acid peak and the new amide and imidazolidone peaks. However, the grafting is not total.
- the melting temperature of the copolymers is identical (105 ° C.) as is the degree of crystallinity (28%).
- the elastic modulus of the LOTADER 3210-g-UD copolymer has a secondary plateau at about 0.15 MPa whereas the LOTADER 3210 copolymer does not.
- the modified polyamide, PADU exhibits an increase in elastic modulus at room temperature and up to a temperature of about 65 ° C and a higher high fluidity at high temperature.
- the samples of HT121 and HT121 grafted are prepared by pressing in the form of disks. These disks are placed in an Ares parallel plate rheometer at 175 ° C, and a frequency sweep test is performed (from 10 Hz to 0.32 mHz) with a deformation imposed of 1%.
- the viscosity at frequencies above 0.2 Hz is the same for both samples.
- the viscosity at low frequencies is significantly increased by grafting.
- a very clear increase in the chain relaxation time is also observed, for the grafted HT121, this time is too long to be measurable in the frequency sweep mode used.
- a copolymer of methyl methacrylate and methacrylic acid (7.5% by number) (Mn 30,000 g / mol) containing 3.3% anhydride functions is chosen. It is noted 72565. 15 g of this polymer are mixed in a twin-screw extruder DSM provided with a recirculation, with 0.64 g of AEIO at 220 0 C for 5 minutes.
- Tg (72565) 130.8 ° C
- Tg (72565grafted) 133.7 ° C
- a flexural creep test in DMA is carried out for 72565 and 72565 grafted, for each compound the test temperature is lower than 10 0 C at Tg.
- a stress of 10 MPa is applied for 2 hours, then the recovery is observed on a 2 hours period.
- Figure 2 shows the profiles of imposed stress and strain measured as a function of time.
- the 72565 has a strain of 9.2% after 2 hours, compared to 7.2% for 72565grafted. Grafting also significantly improves recovery, after 2 hours of recovery 72565 grafted to a residual deformation of 3.8% (almost half of the deformation caused by creep), compared to 6.0% for 72565, which n thus recovered a third of the deformation brought by creep.
- Frequency sweeps are carried out at 175 ° C. in a rheometer with parallel plate geometry. The viscosity at high frequencies is little changed, but at low frequencies, it increases quite significantly.
- ARES parallel plate rheometer analyzes at 150 ° C., under an imposed deformation of 1%, show an increase in the viscous modulus over the entire frequency range (from 10 Hz to 0.32 mHz) as a function of the duration of grafting (the elastic modules are too weak to be accurately measured).
