Claims6
A composition comprising:
- (a) a stereoregular polymer of branched, higher alpha-olefins which has been stabilized with at least one hindered phenol;
- which has been contacted with
- (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;
- in the presence of
- (c) a free radical generator;
- (d) glass;
- (e) at least one epoxy resin;
- (f) at least one epoxy-functional silane;
- and
- (g) a hydroxy-functional compound capable of forming crosslinks and chosen from the group of polymeric and oligomeric hydroxy-functional compounds and mixtures thereof;
- said hydroxy-functional compound having a degree of polymerization of at least 2.
