Abstract
Official abstract text for this publication.
A polymer (A) having, at one terminal moiety thereof, a terminal structure having two or more carbon-carbon unsaturated bonds. A reactive-silicon-group-containing polymer (B) having, at one terminal moiety thereof, a terminal structure having two or more reactive silicon groups.
First claim
Opening claim text (preview).
The invention claimed is: 1. A reactive-silicon-group-containing polymer (B) having, at one terminal moiety thereof, a terminal structure having two or more reactive silicon groups, wherein the reactive-silicon-group-containing polymer (B) is represented by formula (5), wherein R 1 and R 3 are each independently a bivalent bonding group having 1 to 6 carbon atoms and an atom of the bonding group that is bonded to any carbon atom adjacent to the bonding group is any one of carbon, oxygen and nitrogen; R 2 and R 4 are each independently hydrogen, or a hydrocarbon group having 1 to 10 carbon atoms; and n is an integer of 1 to 10; R 5 (s) is/are (each independently) a substituted or unsubstituted hydrocarbon group having 1 to 20 carbon atoms, Y is a hydroxyl group or a hydrolyzable group, and a is 1, 2 or 3; and the reactive-silicon-group-containing polymer (B) is reactive-silicon-group-containing polyoxyalkylene polymer (B). 2. The reactive-silicon-group-containing polymer (B) of claim 1 , having reactive silicon groups which are 1.1 or more in number on average per terminal of the polymer. 3. The reactive-silicon-group-containing polymer (B) of claim 1 , obtained by introducing one or more reactive silicon groups into unsaturated bonds of the polymer (A) according to claim 1 by hydrosilylation reaction. 4. The method for manufacturing a reactive-silicon-group-containing polymer (B) of claim 1 , comprising: introducing one or more reactive silicon groups into unsaturated bonds of the polymer (A) according to claim 1 by hydrosilylation reaction.
