Abstract
Polybutadiene oils of 400-6,000 molecular weight, having double bonds which are 10 to 60% vinyl, 1 to 15% transvinylene and 25 to 85% cis-vinylene, and 3-20% by weight, corresponding to 0.4 to 3% by weight of bound silicon, of which are reactive silyl polymer units of the formula ##STR1## wherein X is a hydrolyzable group and Y and Z are the same as X or are H and/or alkyl of 1-8 carbon atoms, cycloalkyl of 5-12 carbon atoms, or optionally substituted phenyl; are useful as adhesion promoters for vulcanizable elastomer compositions comprising a mineral filler.
