Abstract:
A high molecular weight silicone compound comprising recurring units represented by formula (1), said silicone compound having a weight average molcular weight of 1,000 to 50,000, ##STR92##wherein Z is a divalent to hexavalent, non-aromatic, monocyclic or polycyclic hydrocarbon or bridged cyclic hydrocarbon group having 5 to 12 carbon atoms; Z' is a divalent to hexavalent, normal or branched hydrocarbon group having 1 to 20 carbon atoms or non-aromatic, monocyclic or polycyclic hydrocarbon or bridged cyclic hydrocarbon group having 3 to 20 carbon atoms; Z or Z' may have a nitrogen, oxygen or sulfur atom interposed in a carbon-to-carbon bond, the hydrogen atom on a carbon atom may be replaced by a halogen, alkoxy, nitro, cyano or acetyl group, and a methylene group in the carbon skeleton may be replaced by a carbonyl group;x, y and z are independently integers of 1 to 5 corresponding to the valence of Z and Z';R.sup.1 is a group represented by formula (2a) or (2b); R.sup.2 is a normal, branched or cyclic, substituted or unsubstituted, alkyl or alkenyl group having 1 to 8 carbon atoms or a monovalent, non-aromatic, polycyclic hydrocarbon or bridged cyclic hydrocarbon group having 5 to 12 carbon atoms; ##STR93##wherein R is hydrogen, hydroxyl group or a normal, branched or cyclic alkyl group having 1 to 20 carbon atoms, R' is a normal, branched or cyclic alkenylene group having 1 to 20 carbon atoms, an alkyl R or an alkylene R' group may have an oxygen atom interposed in a carbon-to-carbon bond, some of the hydrogen atoms attached to carbon atoms may be replaced by hydroxyl groups; or R and R', taken together, may form a ring, and each of R and R' is a normal or branched alkylene group of 1 to 8 carbon atoms when they form a ring; andp1 is a positive number and p2, p3 and p4 are 0 or positive numbers and satisfy:p1+p2+p3+p4=1,0<p1/(p1+p2+p3+p4).ltoreq.0.9,0.ltoreq.p2/(p1+p2+p3+p4).ltoreq.0.8,0.ltoreq.p3/(p1+p2+p3+p4).ltoreq.0.7,0.ltoreq.p4/(p1+p2+p3+p4).ltoreq.0.9.
