Abstract
This invention relates to a process for making a thickened thermoset resin composition, comprising: mixing (A) a carboxylic acid containing thermoset resin composition; and (B) at least one compound represented by the formula ##STR1## wherein in Formula (B-I): R.sup.1, R.sup.2, R.sup.3 and R.sup.4 are independently hydrogen or methyl; R.sup.5 is hydrogen, a hydrocarbon group or a substituted hydrocarbon group, the substituents on said substituted hydrocarbon group comprising oxygen and/or nitrogen; and n is at least 1.
Claims17
A process for making a thickened thermoset resin composition for molding materials, comprising:
- mixing
- (A) a thermoset resin composition, wherein said thermoset resin composition comprises at least one of a poly(ester-imide) resin, an epoxy resin, a vinyl ester resin that is a reaction product of an epoxy resin and a monofunctional ethylenically unsaturated carboxylic acid, and a bisphenol A fumarate resin, and the thermoset resin composition optionally contains an amine acceptor;
- and
- (B) at least one compound represented by the formula ##STR8## wherein in Formula (B-I):
- R.sup.1, R.sup.2, R.sup.3 and R.sup.4 are independently hydrogen or methyl;
- R.sup.5 is hydrogen, a hydrocarbon group or a substituted hydrocarbon group, the substituent on said substituted hydrocarbon group is at least one selected from the group consisting of hydroxy, alkoxy, aziridinyl and ester groups;
- and n is at least 1.
A process for making a thickened thermoset resin composition for molding materials, comprising:
- mixing
- (A) a thermoset resin composition comprising at least one of a poly(ester-imide) resin, an epoxy resin, a vinyl ester resin that is a reaction product of an epoxy resin and a monofunctional ethylenically unsaturated carboxylic acid, and a bisphenol A fumarate resin;
- and
- (B) a compound comprising at least two aziridine rings.
A process for making a thickened thermoset composition for molding materials, comprising:
- mixing
