Polymer, process for producing polymer and composition

摘要

The present invention relates to a vinyl polymer terminated in a silanol group, a hydrolyzable silyl group or an acrylic functional group,
to a method of producing a vinyl polymer having a hydrolyzable silyl group at one or more termini thereof
which comprises reacting a vinyl polymer having a silanol group at one or more termini thereof
with a silicon compound having two or more silicon atom-bound hydrolyzable groups,
and a method of producing a vinyl polymer having an acrylic functional group at one or more termini thereof
which comprises reacting a vinyl polymer having a silanol group at one or more termini thereof
with a silicon compound represented by the general formula (3):
€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ XSiR 2 -G-O-C(O)C(L)=CH 2 €ƒ€ƒ€ƒ€ƒ€ƒ(3)
wherein X is a hydrolyzable group.
