Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
71 words
A curable composition which comprises (A) an oxyalkylene polymer having a silicon-containing group with at least one crosslinkable group bonded to a silicon atom and capable of crosslinking by forming a siloxane bond, said crosslinkable group being a member selected from the group consisting of a hydroxyl group and a hydrolyzable group, and (B) hollow microspheres of vinylidene chloride polymer having a true specific gravity of 0.1 g/cm 3 or less.
Claim 2
Dependent Claim
71 words
A curable composition which comprises (A) an oxyalkylene polymer having a silicon-containing group with at least one crosslinkable group bonded to a silicon atom and capable of crosslinking by forming a siloxane bond, said crosslinkable group being a member selected from the group consisting of a hydroxyl group and a hydrolyzable group, and (B) hollow microspheres of vinylidene chloride polymer having a true specific gravity of 0.1 g/cm 3 or less.
