FUNCTIONICIZED POLYMERS AND PARA-ALKYLSTYRENE COPOLYMERS Russian patent published in 2000 - IPC

FIELD: chemistry of polymers. SUBSTANCE: described is functionalized styrene polymer or copolymer containing functionalized para-alkylstyrene groups of formula (I): wherein R₁, R₂ and R₃ are independently selected from group consisting of hydrogen, alkyl, primary and secondary haloalkyl, and R₄ is selected from group consisting of (a), (b), (c) and (d) wherein x is integer from 2 to 10, y is integer from 0 to 20; A is linear hydrocarbon group having from 2 to 10 carbon atoms or branched hydrocarbon group having from 3 to 10 carbon atoms. EFFECT: functionalization of para-alkylstyrene containing polymers with reactive groups which make it possible to introduce said polymers into combined reaction or to combine functionalized polymer with other polymers using grafting method. 11 cl, 5 ex
