Title:

VINYL TERMINATED POLYBUTADIENES CONTAINING URETHANE OR ESTER RESIDUES

Document Type and Number:

WIPO Patent Application WO2000026269

Kind Code:

A8

Abstract:

Thermosetting polymers and the electrical laminates made therefrom are disclosed. The polymer comprises the cross-linked product of: a) one or more ethylenically unsaturated aromatic monomers, optionally containing a halogenated monomer to impart fire retardation, and b) a vinyl-terminated polybutadiene or butadiene-styrene copolymer containing either a urethane or an ester group. It has been discovered that an unexpected combination of thermal, electrical, and mechanical properties are obtained from the composition recited herein. The composition is ideally suited as a matrix polymer for electrical substrate applications.
