Abstract
Abstract A curable composition comprising (A) 100 parts by weight of an organic polymer having at least one cross-linkable group containing a silicon atom to which a hydrolyzable group is bonded, and (B) 10 to 500 parts by weight of a vinyl chloride polymer. In the curable composition of the present invention, the viscosity is not lowered even after the storage for a long time and therefore the workability as sealants is not lowered.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
62 words
A curable composition comprising, (A) 100 parts by weight of an organic polymer having in its molecule at least one cross-linkable group containing a silicon atom to which a hydrolyzable group is bonded, said cross-linkable group being cross-linkable to produce an elastomer by the formation of a siloxane bond, and (B) 10 to 500 parts by weight of a vinyl chloride polymer.
Claim 2
Dependent Claim
62 words
A curable composition comprising, (A) 100 parts by weight of an organic polymer having in its molecule at least one cross-linkable group containing a silicon atom to which a hydrolyzable group is bonded, said cross-linkable group being cross-linkable to produce an elastomer by the formation of a siloxane bond, and (B) 10 to 500 parts by weight of a vinyl chloride polymer.
Claim 3
Dependent Claim
21 words
The composition of Claim 1, wherein said organic polymer (A) has a molecular weight in the range of 300 to 1,000,000.
