Claims19
A composition comprising:
- (a) a stereoregular polymer of a branched alpha-olefin containing 4-12 carbon atoms per molecule which has been stabilized with at least one hindered phenol;
- (b) a grafting compound selected from the group consisting of vinyl-polymerizable, unsaturated, hydrolyzable silanes;
- carboxylic acids;
- carboxylic acid derivatives:
- carboxylic acid anhydrides:
- carboxylic acid anhydride derivatives;
- and mixtures thereof:
- (c) a free radical generator;
- (d) glass;
- and
- (e) at least one hydroxy-functional compound selected from the group consisting of poly(hydroxyethers);
- condensation polymerization products formed from polyhydroxy alcohols, polycarboxylic acids and hydroxy-functional acids;
- and addition polymerization products formed from hydroxy-functional vinyl unsaturated monomers.
