THERMOPLASTIC COMPOSITION CONTAINING THE MATRIX AND THE HYPERBRANCHED POLYMERIC ADDITIVE INCOMPATIBLE WITH THE MATRIX, AND THE PRODUCTS PRODUCED FROM THIS MATERIAL Russian patent published in 2007 - IPC C08L77/00 C08L77/02 C08L77/06 C08J3/05 C08G83/00 C08G69/26 

FIELD: chemical industry; production of the thermoplastic compositions containing the matrixes and the hyperbranched polymeric additives.

SUBSTANCE: the invention represents the thermoplastic composition including: - the matrix made from the thermoplastic copolyamide of the type of the copolyamides produced by the reaction of polycondensation of the diacids and diamines; and, at least, one additive being the modifying agent of interaction of the matrix, at least with one agent; at that this additive is formed, at least, by one polymeric compound, which is hyperbranched functional radical R² by means of its end groups. At that this R² means the substituted or non-substituted hydrocarbon radical of the silicon type, the linear or branched alkyl, aromatic, arylalkyl, alkylaryl cycloaliphatic type, which may include one or several nonsaturated links and-or one or several heteroatoms. At that the matrix and the hyperbranched functional polymeric additive are incompatible, and the hyperbranched functional polymeric compound is soluble in the matrix. The composition allows to control the hydrophobic property of the thermoplastic products made out of polyamides.

EFFECT: the invention allows to control the hydrophobic property of the thermoplastic products made out of polyamides.
