| 20080221272 | Polymer Material Comprising Chains Bearing Imidazolidone Functions - The invention concerns a polymer material consisting of macromolecular chains bound by hydrogen bonds wherein: the macromolecular chains consist of a polymer skeleton whereon is fixed by at least one covalent bond a modifying agent, the modifying agent comprising, assembled in a common molecule, one or more associative groups capable of being bound by hydrogen bonds and one or more reactive groups capable of forming covalent bonds with the polymer skeleton, at least one of the associative groups of the modifying agent is an imidazolidone heterocycle, the macromolecular chains bear on average 1 to 10 imidazolidone groups per chain. The average number of imidazolidone groups to be introduced into the macromolecular chains depends both on the average mass of said chains and the final properties desired for the material. The inventive polymer material can be extruded, co-extruded, injected, blown, moulded, overmoulded, calandered, thermoformed. It can be used to produce articles such as tubes, films, plates, extruded strings, bottles, containers. The inventive polymer material can also be mixed with other materials such as other polymers, thus it is used for example as impact modifier or rheology regulator. The invention further concerns the use of said polymer material as compatibility agent in a composition comprising among others at least two polymers belonging to different classes of polymers. | 09-11-2008 |
| 20090062551 | ELASTIC MATERIALS - The present invention relates to materials exhibiting the property of rubbery elasticity, consisting of molecules with a mass of between 9 and 9000 g/mol, all or some of the molecules having at least three groups (also referred to as “associative groups”) capable of associating via non-covalent interactions. | 03-05-2009 |
| 20100120983 | STYRENE/ANHYDRIDE POLYMERIC MATERIAL AND GRAFT HAVING ENHANCED PROPERTIES - A polymeric material from the styrene family, consisting of macromolecular chains grafted by nitrogen-containing heterocyclic groups; wherein the macromolecular chains consist of a polymeric backbone to which a grafted agent is attached by at least one covalent bond, the grafting agent comprises, in a single molecule, one or more associative groups capable of being bound by hydrogen bonds, and one or more reactive groups capable of forming covalent bonds with the polymeric backbone, at least one of the associative groups of the modifier is an imidazolidone heterocyclic ring. The mean number of imidazolidone groups to be inserted into the macromolecular chains is dependent both on the mean mass of said chains and on the final properties to be imparted to the material. The polymeric material of the invention can be extruded, coextruded, injected, blow-moulded, moulded, overmoulded, calendered or thermoformed. Objects such as tubes, films, plates, stiffenerss, bottles and containers can be made. The polymeric material of the invention can also be blended with other materials such as other polymers, and can thus be modified by elastomeric phases that enhance the impact strength thereof. The polymeric material of the invention can be a component of masterbatches of additives such as pigments and fillers. The present invention further relates to the use of said polymeric material as a compatibilization agent in a composition including, inter alia, at least two polymers belonging to different polymeric classes.” | 05-13-2010 |
