HYDROCARBON POLYMERS WITH TWO ALKOXYSILANE END GROUPS
An alkoxysilane-terminated hydrocarbon polymer of formula (1): Formula (1) in which: - is a double or single bond; - Each of R2, R3, R4 and R5 is H, a halogen, an alcoxycarbonyl or an alkyl, - m and p are each from 0 to 5, - each of R and R' is an alkyl, - Z is an alkylene, interrupted or not by COO, - q is 0 or 1, - r is 0, 1 or 2, and - n is an integer such that the number average molecular weight Mn of the polymer is from 400 to 50,000 g/mol, and the polymolecularity (PDI) of same is from 1.0 to 2.0. Preparation by polymerisation by ring-opening metathesis for 2 hours to 24 hours. Adhesive composition comprising the polymer (1) and crosslinking catalyst. Bonding by assembling two substrates using this adhesive composition.
