Abstract
Abstract The incorporation of a combination of (1) a bromine-releasing flame-retarding compound (e.g., tetrabromobenzene, hexabromobenzene, decabromobiphenyl, decabromodiphenyl oxide, etc.) and (2) chromium naphthenate in a polybutadiene resin, renders the resin flame resistant.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
86 words
A peroxide-cured or peroxide-curable polybutadiene polymer or copolymer resin which includes as a flame-retarding agent, 2 to 20 parts of an aromatic bromine-releasing flame-retarding agent to 0.25 to 10 parts of chromium naphthenate, the parts being by weight, and the resin being from the class consisting of homopolymers of butadiene and copolymers of butadiene and styrene containing at least 40 percent by weight of butadiene, and at least 80 percent by weight of the butadiene repeating units in the homopolymer or copolymer being in the 1,2-configuration.
