HYDROCARBON POLYMERS HAVING AN ALKOXYSILANE END GROUP

摘要

The invention relates to a polymer of formula (1) with alkoxysilane ending: (1) in which: is a double or single bond; each of R2, R3, R4 and R5 is H, a halogeno, an alcoxycarbonyl or an alkyl, m and p are each 0 to 5, each of R and R' is an alkyl, Z is an alkylene, optionally interrupted by COO, q is 0 or 1, r is 0, 1 or 2, and n is such that the number-average molar mass of polymer (1) is 400 to 50,000 g/mol and the polymolecularity of polymer (1) is 1.0 to 2.0. The invention also relates to a preparation by ring-opening metathesis polymerisation. The invention further relates to the use thereof as an adhesion promoter or a reactive plasticiser.
