Abstract:
A functionalized olefin/cycloolefin/alkylstyrene copolymer, which is obtained from reacting:(i) an olefin/cycloolefin/alkylstyrene copolymer obtained from copolymerizing the following monomers: (A) 0.1-50 mol % of an alkylstyrene represented by formula (I) wherein R1 and R2 are independently selected from the group consisting of hydrogen, alkyl, and primary and secondary haloalkyl; (B) 1-99 mol % of a cycloolefin represented by formula (II) wherein a is an integer from 0 to 3, R3, R4, R5, R6, R8, R9, R10, and R11 can be the same or different and are selected from the group consisting of hydrogen, halogen, C1-10 alkyl, and haloalkyl and R12 and R13 can be the same or different and are selected from the group consisting of hydrogen, halogen, C1-10 alkyl, haloalkyl, aryl, haloaryl, alcohol, ester, and acid, and optionally R12 and R13 can be bonded together to form formula (III) wherein R14 and R15 can be the same or different and are selected from the group consisting of hydrogen, halogen, C1-10 alkyl, and haloalkyl and b is an integer from 3 to 5; (C) 0.1-98.9 mol % of a monomer selected from the group consisting of ethylene, a C3-20 &agr;-olefin, and mixtures thereof; and (D) a non-conjugated diene present in an amount of more than 0 mol % and less than 50 mol %; and (ii) a compound which is reactive with a double bond, such that a double bond of the non-conjugated diene is functionalized to form a group selected from epoxy, halogen, ether, alcohol, sulfate, borane, borate, aldehyde, and ketone.
