Homo- and copolymers of 1,3-dienes containing reactive silyl groups, and their preparation and use
First Claim
1. A process for preparing a homo- or copolymer of a 1,3-diene carrying reactive silyl groups and having 0.4-12% by weight of bound silicon consisting essentially of, reacting of 1,3-diene homo- or copolymer having a molecular weight (Mn) of 400-8,000 and containing less than 1% of its aliphatic double bonds in conjugation, at a temperature of 150°
- -300°
C., with a silicon compound of the formula ##STR6## wherein R is an unsaturated aliphatic hydrocarbon residue of 2-20 carbon atoms,X is halogen, C1-6 alkoxy, C1-6 alkoxyalkoxy, C6-12 aryloxy, C1-8 alkanoyloxy, C1-6 ketoximato or C1-12 hydrocarbylamido,Y and Z independently are one of the X groups, hydrogen, alkyl of 1-8 carbon atoms, cycloalkyl of 5-12 carbon atoms, or optionally substituted phenyl.

Abstract
A homo- or copolymer of a 1,3-diene having reactive silyl groups bound thereto, and containing 0.4-12% by weight of bound silicon, prepared by reacting at a temperature of 150°-300° C., a 1,3-diene homo- or copolymer, having less than 1% of its aliphatic double bonds conjugated and having a molecular weight (Mn) of 400-8,000, with a silicon compound of the formula ##STR1## wherein R is an unsaturated aliphatic hydrocarbon residue of 2-20 carbon atoms,
X is halogen, C1-6 alkoxy, C1-6 alkoxyalkoxy, C6-12 aryloxy, C1-8 alkanoyloxy, C1-6 ketoximato or C1-8 hydrocarbylamido,
Y and Z independently are one of the X groups, hydrogen, alkyl of 1-8 carbon atoms, cycloalkyl of 5-12 carbon atoms, or optionally substituted phenyl.
