MULTI-ARM BLOCK COPOLYMER, AND PRESSURE SENSITIVE ADHESIVE AND TAPE EMPLOYING A MULTI-ARM ELASTOMERIC BLOCK COPOLYMER |
摘要 |
The present invention provides a novel pressure- sensitive adhesive made from a multi-arm elastomeric block copolymer, and a novel tape made therefrom. The multi-arm block copolymer has the general structure (A'-B)m Y wherein A' and B are polymer segments, Y is a residue of a multifunctional coupling agent and m is the number of arms and is at least 3. A' comprises a random copolymer of a monoalkenylarene and a conjugated diene, wherein the Tg of A' is less than 19.degree.C. B comprises either a homopolymer of a conjugated diene or a polymer of two or more conjugated dienes.
