Claims Analysis
Total Claims: 23
Claim 1
Independent Claim
34 words
A composition comprising poly(arylene sulfide), titanium dioxide and 3-mercaptopropyltrimethoxysilane; wherein the amount of titanium dioxide and 3-mercaptopropyltrimethoxysilane present is sufficient to increase the resistance of the poly(arylene sulfide) composition to carbonization and track formation.
Claim 2
Dependent Claim
34 words
A composition comprising poly(arylene sulfide), titanium dioxide and 3-mercaptopropyltrimethoxysilane; wherein the amount of titanium dioxide and 3-mercaptopropyltrimethoxysilane present is sufficient to increase the resistance of the poly(arylene sulfide) composition to carbonization and track formation.
Claim 3
Dependent Claim
14 words
A composition in accordance with claim 1 wherein said poly(arylene sulfide) is poly(p-phenylene sulfide).
Claim 4
Dependent Claim
10 words
A composition in accordance with claim 1 further comprising talc.
Claim 5
Dependent Claim
11 words
A composition in accordance with claim 1 further comprising glass fibers.
