Claims Analysis
Total Claims: 23
Claim 1
Independent Claim
21 words
A composition comprising poly(arylene sulfide), glass and at least one organosilane selected from the group consisting of: 3-N-(Trimethoxysilylpropyl)poly(ethylenimine), Diethylamino-3-trimethoxysilylpropyldisulfide, and 3-(Diethylamino)propyltrimethoxysilane.
Claim 2
Dependent Claim
21 words
A composition comprising poly(arylene sulfide), glass and at least one organosilane selected from the group consisting of: 3-N-(Trimethoxysilylpropyl)poly(ethylenimine), Diethylamino-3-trimethoxysilylpropyldisulfide, and 3-(Diethylamino)propyltrimethoxysilane.
Claim 3
Dependent Claim
47 words
A composition in accordance with claim 1 wherein said at least one organosilane is present in an amount sufficient to increase the flow rate of said poly(arylene sulfide) upon heating of the composition to a temperature of at least about the melting point of said poly(arylene sulfide).
Claim 4
Dependent Claim
28 words
A composition in accordance with claim 1 wherein the amount of said at least one organosilane is about 0.2 to about 2 weight percent based upon total composition.
Claim 5
Dependent Claim
14 words
A composition in accordance with claim 1 wherein said poly(arylene sulfide) is poly(phenylene sulfide).
Claim 6
Dependent Claim
16 words
A composition in accordance with claim 2 or 3 wherein said poly(arylene sulfide) is poly(phenylene sulfide).
Claim 7
Dependent Claim
12 words
A composition in accordance with claim 1 wherein said organosilane is 3-N-(Trimethoxysilylpropyl)poly(ethylenimine).
Claim 8
Dependent Claim
12 words
A composition in accordance with claim 1 wherein said organosilane is diethylamino-3-trimethoxysilylpropyldisulfide.
Claim 9
Dependent Claim
12 words
A composition in accordance with claim 1 wherein said organosilane is 3-(Diethylamino)propyltrimethoxysilane.
