Definitions
- the present invention relates to novel carboxy-functional polyesters and diester derivatives which can be prepared by ring-opening reaction of an anhydride with a hydroxy-functional precursor. While the hydroxy-functional precursor has a hydrophobic character, the ring-opening reaction gives rise to free carboxyl groups and consequently an amphiphilic molecular character of the resulting poly- or diester derivative.
- the polyesters and diester derivatives according to the invention have outstanding performance properties.
- polyesters and diester derivatives and their use are known.
- polyesters are used, for example, as film formers in coating compositions such as paints and inks.
- esters are also used, for example, depending on the composition and properties, as additives for achieving a wide variety of properties in coating compositions such as paints and coatings. It is also possible that such polyesters and diester derivatives develop their properties by specific combination with other components such as additives, pigments and / or fillers.
- WO 2010/130312 A1 discloses the use of a specific combination of a specific polyester with layered inorganic particles, for example mixed hydroxides, in aqueous systems, these systems having liquid-crystalline properties. These liquid-crystalline systems, when used in aqueous coating compositions, result in excellent chip resistance of coatings produced using these coating compositions.
- WO 2010/130308 likewise discloses a combination of polyester and mixed hydroxides or hydrotalcites in the aqueous phase and the use of these liquid-crystalline systems in aqueous effect water-based paints. The optical properties, in particular the achievement of metallic effects (flop) and brightness of finishes produced with the effect paints are outstanding.
- Liquid-crystalline systems are those which, in addition to typical properties of a liquid, in particular a certain flowability or fluidity, also have typical properties of a crystal, in particular therefore a certain structural anisotropy.
- Such systems can be, for example, thermotropic, that is their liquid-crystalline properties occur depending on the temperature.
- lyotropic systems in such systems, in the presence of a solvent, such as water, and amphiphilic organic components, such as surfactants, liquid crystallinity is achieved within certain ranges of concentration. If structural anisotropy is present, an optical anisotropy is regularly also given, that is to say such systems show the known phenomenon of birefringence. The systems therefore have different refractive indices for different polarization and direction of the incident light.
- the birefringence causes under the polarizing microscope (ie crossed polarizers, namely the primary filter or the linear polarizer of the light of the light source and this rotated by 90 ° secondary filter or analyzer) in spite of the aforementioned filter arrangement and unlike purely isotropic systems, not complete extinction occurs, but a portion of the light penetrates through the analyzer and thus can be detected.
- crossed polarizers namely the primary filter or the linear polarizer of the light of the light source and this rotated by 90 ° secondary filter or analyzer
- the object of the present invention was therefore to provide new components with which systems with particularly pronounced liquid-crystalline properties can be produced.
- components should be provided which can lead to these liquid-crystalline properties in aqueous systems.
- the systems should be as simple as possible and the achievement of a remplissigkristallintician can be made possible without the costly addition of other compounds.
- the components should, on their own and without the addition of further compounds in or with water, lead to liquid-crystalline phases. Even if the combination with other compounds can be offered in different cases, it should therefore be possible to use the components alone in water and thereby to form liquid-crystalline phases. In this way, it should be possible to combine the anisotropic, ordered properties of crystalline systems with the proper formability of a liquid or a flowable system.

- anhydride (A) To prepare the polyesters and diesters of the invention, at least one anhydride (A) of the following formula (I) is used:
- Ri H, d- to C4-s alkyl, C 2 to C 4 s-alkenyl, C6- preferably up to 4 C s alkyl, C 6 to C 4 s-alkenyl, more preferably Ce to C 4 s Alkenyl and most preferably Ce to C2 4 alkenyl.

- the alkyl and alkylene radicals can be linear or branched. In this case, the carbon-carbon double bond in the alkylene radicals can be arranged as desired.
- the succinic anhydride derivatives are prepared by the reaction of maleic anhydride with alpha olefins. This initially produces a corresponding alkenyl-modified succinic anhydride derivative, which can then also be used in the context of the present invention.
- Such a derivative then contains a carbon-carbon double bond in the beta-gamma position as viewed from the anhydride ring.

- polyester derivatives for the preparation of the polyester derivatives as component (B) linear, hydroxy-functional polyesters (B1) are used.
- a polyester is usually referred to a polymeric organic compound which is prepared using polyhydric organic alcohols and polybasic organic carboxylic acids. The alcohols and carboxylic acids are linked together by esterification, ie by condensation reactions. Accordingly, the polyesters are usually assigned to the group of polycondensation resins.
- the anhydrides of the carboxylic acids in particular the anhydrides of dicarboxylic acids, can also be used instead of or in addition to the corresponding organic carboxylic acids.
- anhydride is thus to be understood as meaning a carboxylic acid anhydride.
- Linear products such as the polyester (B1) to be used according to the invention are obtained, in particular, when difunctional starting components (diols, dicarboxylic acids) are used.
- the term linear polyester in the context of the present invention thus means that the polymer backbone, that is to say the sequence of ester bonds which make up the linking of the individual polyester building blocks, has a linear character.
- the individual compounds used for the preparation thus each have two functional groups capable of ester bonding, that is to say in particular hydroxyl groups, carboxyl groups, and / or anhydride groups.

For example, reference is made to the dimer fatty acids described below. However, these compounds are also to be designated as starting compounds which are incorporated by appropriate polymerization reactions in the polyester and then make up a non-independent proportion of the polyester. Consequently, these starting compounds are also referred to as monomers.

- the acyclic aliphatics may be linear or branched.
- Linear in this context is known to mean that the respective compound has no branches with respect to the carbon chain, but the carbon atoms are arranged exclusively in a linear sequence in a chain.
- Branched or non-linear means in the context of the present invention that the respective considered compound has a branch in the carbon chain, that is, unlike the linear compounds at least one carbon atom of the respective compound is a tertiary or quaternary carbon atom.
- Cyclic aliphatics or cycloaliphatic compounds are those compounds in which at least part of the carbon atoms present in the molecule are linked in such a way that that one or more rings are formed.

What has been said above is that the proportion of monomers (b2) depends on whether and in what proportion as monomers (b1) dimeric fatty acids and thus the said commercial products are used.
- monomers (b1) for example, exclusively or predominantly hydrogenated bisphenols and / or dimeric aliphatic fatty alcohols (which are obtained regularly by hydrogenation of dimeric aliphatic fatty acids, in which case the regularly present monomers (b2) are also hydrogenated and thus monomers (b1) , namely dimeric aliphatic fatty alcohols, reduced are used), the proportion of monomers (b2) is correspondingly lower. If exclusively or predominantly dimeric aliphatic fatty acids are used, then the proportions of the monomers (b2) are obviously higher as a rule.
- the following monomers can preferably be used in the preparation of the polyester (B1):
- linear aliphatic, cycloaliphatic and / or aromatic dicarboxylic acids having 4 to 12 carbon atoms in particular oxalic acid, malonic acid, succinic acid, glutaric acid, adipic acid, sebacic acid, maleic acid, fumaric acid, isophthalic acid, terephthalic acid, orthophthalic acid,

- the storage modulus G ' is an expression of the elasticity of a sample (ie, the elastic, for example, gel-like properties reflect a sample and thus the elastic deformation after energy input)
- the loss modulus G reflects the dissipatively released or lost viscous portion of the energy introduced into the sample and is therefore fundamentally an expression of a fluid character
- Systems in which the storage modulus G 'is significantly larger than the loss modulus G" have virtually no fluid character in particular, are therefore not flowable.
- such systems In contrast to a fluid and flowable character, such systems generally gel-like character, which leads in particular to a much more difficult formability and operational capability.
- such gel-like systems can hardly form homogeneous mixtures with other components.
- compositions according to the invention have approximately the same magnitude of loss modulus G "and storage moduli G 'over a broad shear stress range (0.2 to 100 Pa.)
- the amounts of loss modulus G" and storage modulus G' differ at a shear stress of 10 Pa only about 442 Pa (composition E1), 434 Pa (composition E2) and 34 Pa (composition E3), wherein in each case the loss modulus G "is greater than the storage modulus G.”
- Similar conditions also result at higher or lower shear stresses are each of similar magnitude, wherein for the compositions E1 and E2 the loss modulus G "over the entire range is greater than the storage modulus G 'and for the composition E3 at shear stresses of less than 5 Pa, the storage modulus is only slightly larger than the loss modulus (Figure Figure 5 shows the loss modulus and storage modulus of the measured samples over the whole gemes SEN range of shear stress).
- the composition V1 is a non-flowable gel, which can not be processed with conventional laboratory or larger stirring devices such as dissolvers and accordingly has a very poor formulatability.
- compositions according to the invention retain their liquid-crystalline character over a wide range of mechanical stress (shear stress) while the non-inventive composition has a gel-like character.
