Abstract
A polymer which is prepared by polymerizing at least one ethylenically unsaturated monomer in the presence of an organic polymer having at least one reactive silicone group in a molecule and a compound having at least two independent ethylenically unsaturated functional groups in a molecule by use of a radical polymerization initiator having a reactive silicone group and/or a chain transfer agent having a reactive silicone group, which is cured with moisture to give a product having improved properties such as tensile properties and weather resistance.
Claims13
A polymer which is prepared by addition polymerizing at least one ethylenically unsaturated monomer in the presence of:
- (A) an organic polymer having, in a molecule, at least one reactive silicone group of the formula:
- ##STR27## wherein R.sup.4 is a C.sub.1 -C.sub.20 alkyl group, a C.sub.6 -C.sub.20 aryl, a C.sub.7 -C.sub.20 aralkyl group or a triorganosiloxane group of the formula:
- (R").sub.3 SiO--
- in which R" is, the same or differant, C.sub.1 -C.sub.20 hydrocarbon group, X is a hydroxyl group or, the same or different, a hydrolyzable group, a is an integer of 0 to 3, b is 0, 1 or 2 and m is an integer of 1 to 18, said polymer being selected from the group consisting of a polyalkyleneoxide, a polyester and an ether-ester block copolymer,
- (B) a compound having at least two independent ethylenically unsaturated group in a molecule, and
- (C) at least one component selected from the group consisting of a radical polymerization initiator having a reactive silicone group (I), a chain transfer agent having a reactive silicone group (I) and a mixture thereof.
