Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
34 words
A water curable polymer of a hydrolyzable, azide sulfonyl silane and a substantially linear, low pressure ethylene polymer having a density of about 0.850 to about 0.970, preferably of about 0.890 to about 0.930.
Claim 2
Dependent Claim
34 words
A water curable polymer of a hydrolyzable, azide sulfonyl silane and a substantially linear, low pressure ethylene polymer having a density of about 0.850 to about 0.970, preferably of about 0.890 to about 0.930.
Claim 3
Dependent Claim
33 words
A water curable polymer as defined in claim 1 wherein the substantially linear, low pressure ethylene polymer is an interpolymer of ethylene and at least one C 3 to C 8 alpha olefin.
Claim 4
Dependent Claim
47 words
A water curable polymer as defined in one or both of the claims to 2 wherein the hydrolyzable azide sulfonyl silane has the formula: wherein R is a hydrocarbon radical, each V is hydrogen, a hydrocarbon radical or a hydrolyzable group and Z is a hydrolyzable group.
Claim 5
Dependent Claim
23 words
A water curable polymer as defined in claim 3 wherein R is ethyl benzene, each V and Z are alkoxy radicals especially methoxy.
Claim 6
Dependent Claim
25 words
A water curable polymer as defined in claim 1 wherein the said silane is 2-(trimethoxysilyl)ethylbenzene sulfonyl azide and the ethylene polymer is an ethylene-butene-1 copolymer.
Claim 7
Dependent Claim
16 words
The crosslinked product of the polymer of one or more of the claims 1 to 5.
Claim 8
Dependent Claim
18 words
A reactive composition comprising a hydrolyzable azide sulfonyl silane and an ethylene polymer, as defined in claim 1.
Claim 9
Dependent Claim
40 words
A reactive composition as defined in claim 7 wherein the hydrolyzable azide sulfonyl silane has the formula: wherein R is a hydrocarbon radical, each V is hydrogen, a hydrocarbon radical or a hydrolyzable group and Z is a hydrolyzable group.
Claim 10
Dependent Claim
21 words
A reactive composition as defined in claim 8 wherein R is ethylbenzene, each V and Z are alkoxy radicals especially methoxy.
Claim 11
Dependent Claim
