Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
65 words
A one component curing composition comprising (A) a vinyl polymer having on the polymer chain end or the side chain thereof at least one silicon atom to which a hydrolyzable group is linked, per one polymer molecule, the main chain of the vinyl polymer consisting essentially of a polymer of a vinyl compound, and (B) an acid phosphoric compound containing a linkage in the molecule.
Claim 2
Dependent Claim
65 words
A one component curing composition comprising (A) a vinyl polymer having on the polymer chain end or the side chain thereof at least one silicon atom to which a hydrolyzable group is linked, per one polymer molecule, the main chain of the vinyl polymer consisting essentially of a polymer of a vinyl compound, and (B) an acid phosphoric compound containing a linkage in the molecule.
Claim 3
Dependent Claim
30 words
The composition of Claim 1, wherein the acid phosphoric compound (B) is a compound of the general formula: wherein n is 1 or 2 and R is an organic residue.
Claim 4
Dependent Claim
21 words
The composition of Claim 1, wherein the acid phosphoric compound (B) is a titanate coupling agent containing linkage in the molecule.
Claim 5
Dependent Claim
33 words
The composition of Claim 1, wherein the acid phosphoric compound (B) is present in an amount of 0.01 to 10 parts by weight per 100 parts by weight of the vinyl polymer (A).
