Abstract
A copolymer composition and coating comprising the copolymer composition containing a vinyl silane of the formula ##STR1## where R.sub.1 is an aryl or alkyl group having 1 to 10 carbon atoms and R.sub.2 is a hydrolysable group; and a vinyl ester of a branched fatty acid having the formula ##STR2## wherein R.sub.3, R.sub.4, R.sub.5 are hydrogen or alkyl groups with 1 to 12 carbon atoms and wherein the total of R.sub.3, R.sub.4 and R.sub.5 contain at least 3 carbon atoms and optionally at least one olefinically unsaturated compound.
Claims17
A crosslinkable copolymeric composition having a weight average molecular weight below about 40,000, a hydroxyl value from about 20 to 160, and an acid value below about 20, derived from A, B and optionally, C, wherein:
- A is 5 to 95% by weight of A, B and C of a vinyl silane having the formula:
- ##STR12## where R.sub.1 is an aryl or alkyl group having 1 to 10 carbon atoms and R.sub.2 is a hydrolysable group;
- B is 5 to 95% by weight of a vinyl ester of a branched fatty acid having the formula ##STR13## wherein R.sub.3, R.sub.4, R.sub.5 are hydrogen or alkyl groups with 1 to 12 carbon atoms and
- wherein the total of R.sub.3, R.sub.4 and R.sub.5 contain at least 3 carbon atoms;
- and
- C is 0 to 90% by weight of a different polymerizable olefinically unsaturated compound.
