摘要

Process for obtaining polymers containing reactive silane groups, in the main chain and/or as terminal groups and/or in the side chains, of the general formula: ** (See formula) ** in which ** (See formula) ** R'= H, alkyl, (preferably C1-C6); aryl (preferably C6-C10); alkylaryl; or arylalkyl X - halogen (chlorine, bromine, iodine or fluorine) or OR' b, g = 0 or 1 f = 0 - 100, where b and/or g = 1 f - 1 - 100, where b and/or g = 0 m = 0 - 1,000 c - 0 - 10,000 d = 0 - 10,000 e = 0 - (c + d) (c + d) 0 Y PcQdRe represents a chain unit having a molecular weight of 54 to 1,000,000, in which the individual elements P, Q and R may be present in any order; characterized in that a cyclic monoolefin and/or a polybutadiene, a polypropylene and/or a polybutadiene/styrene copolymer, is reacted, in the presence of an olefinically unsaturated reactive silane, at a temperature of -60 to + 60º on a catalyst compound a) a compound of rhenium, tantalum, molybdenum or tungsten and b) an organometallic compound of a metal from group 1a to group 4a of the periodic system.
