525/09200B

Abstract:

A crosslinkable composition comprising from 50 to 98 percent by weight of an epoxidized monohydroxylated polydiene polymer which is comprised of at least two polymerizable ethenically unsaturated hydrocarbon monomers wherein at least one is a diene monomer which yields unsaturation which is suitable for epoxidation, and from 50 to 2 percent by weight of an amino resin. The preferred polymer for use herein has the formulawherein A and B are polymer blocks which may be homopolymer blocks of conjugated diolefin monomers, copolymer blocks of conjugated diolefin monomers, or copolymer blocks of diolefin monomers and monoalkenyl aromatic hydrocarbon monomers, S is a vinyl aromatic hydrocarbon block, x and y are 0 or 1 and either x or y must be 1 but only one at a time can be 1, and z is 0 or 1, and contains from 0.2 to 7.0 meq of epoxy per gram of polymer.

International Classification:

C08L053/00

US Classification:

525/088000

Abstract:

The present invention relates to gels prepared from novel anionic block copolymers of mono alkenyl arenes and conjugated dienes, and to blends of such block copolymers with other polymers. The block copolymers are selectively hydrogenated and have mono alkenyl arene end blocks and controlled distribution blocks of mono alkenyl arenes and conjugated dienes. The block copolymer may be combined with tackifying resins, oils and other components to form the gels of the present invention.
