Abstract
The present disclosure provides a curable composition containing a benzoxazine, reactive diluent and a soluble polyimide. The curable composition, upon curing, renders an article having well balanced thermal, chemical and mechanical properties and may be used in a variety of applications, such as in coatings, structural composites and encapsulating systems for electronic and electrical components.
Claims15
A curable composition comprising:
- (a) a benzoxazine;
- (b) a reactive diluent;
- and
- (c) a soluble polyimide derived from (i) a phenylindane diamine and (ii) a phenylindane dianhydride and/or dianhydride.
A process for producing a curable composition comprising (a) mixing a soluble polyimide derived from (i) a phenylindane diamine and (ii) a phenylindane dianhydride and/or a dianhydride with a reactive diluent and optional additive(s) to produce a homogeneous solution or dispersion;
- (b) mixing a benzoxazine with the homogenous solution or dispersion to form the curable composition.
A curable composition comprising:
- (a) about 40% by weight to about 90% by weight of a benzoxazine;
- (b) about 1% by weight to about 40% by weight of a reactive diluent;
- and
- (c) about 0.1% by weight to about 25% by weight of a soluble polyimide derived from (i)
- a phenylindane diamine and (ii) a phenylindane dianhydride and/or a dianhydride where the percent by weights are based on the total weight of the curable composition.
