Abstract
Disclosed is a nonstyrenated polyester or vinyl ester resin that is found to be nonbrittle and to have good temperature performance, relative to known nonstyrenated polyesters or vinyl esters. Also disclosed is a nonstyrenated polyester or vinyl ester urethane acrylate resin. Methods for making nonstyrenated polyester or vinyl ester resins, including urethane acrylate resins, are provided.
Claims19
A nonstyrenated thermoset resin composition comprising at least one urethane methacrylate, prepared from a reaction mixture consisting essentially of a hydroxylated methacrylate and an isocyanate, at least one resin selected from the group consisting of unsaturated polyesters, unsaturated polymers of vinyl esters, and unsaturated polymers of dicyclopentadiene, and combinations thereof, and a hydroxylated methacrylate monomer.
A nonstyrenated thermoset resin composition comprising at least one urethane methacrylate prepared from a reaction mixture consisting essentially of a hydroxylated methacrylate and an isocyanate, and at least one resin selected from the group consisting of unsaturated polymers of vinyl esters and unsaturated polymers of dicyclopentadiene, and combinations thereof.
A method for producing a nonstyrenated thermoset resin composition comprising the steps of:
- (a) combining a urethane methacrylate, prepared from a reaction mixture consisting essentially of a hydroxylated methacrylate and an isocyanate, with at least one resin selected from the group consisting of unsaturated polyesters, unsaturated polymers of a vinyl ester, and unsaturated polymers of dicyclopentadiene, and combinations thereof,
- (b) mixing the urethane methacrylate and the resin of step (a) under conditions that cause the temperature of the mixture to increase to between about 120° F. and 250° F. to form a mixture and maintaining the temperature of the mixture between about 120° F. and 250° F. for a time period;
- (c) allowing the mixture of step (b) to cool to a temperature of about 90° F. or less;
- and
- (d) mixing a hydroxyethyl methacrylate monomer into the mixture of step (c) in an amount sufficient to change the viscosity of the composition.
A method for producing a nonstyrenated thermoset resin composition comprising the steps of:
- (a) combining a urethane methacrylate prepared from a reaction mixture consisting essentially of a hydroxylated methacrylate and an isocyanate, with at least one resin selected from the group consisting of unsaturated polymers of a vinyl ester and unsaturated polymers of dicyclopentadiene, and combinations thereof, the urethane methacrylate and the resin being present in a ratio (w/w) of between about 1:9 and 9:1;
- (b) mixing the resin and the urethane methacrylate of step (a) under conditions that cause the temperature of the mixture to increase to between about 120° F. and 250° F. to form a mixture and maintaining the temperature of the mixture between about 120° F. and 250° F. for a time period;
- and
- (c) allowing the mixture of step (b) to cool.
A nonstyrenated thermoset resin composition comprising:
- a urethane methacrylate, prepared from a reaction mixture consisting essentially of two monomers, the first monomer being a hydroxylated methacrylate selected from the group consisting of hydroxyethyl methacrylate and hydroxyethyl propyl methacrylate, and the second monomer being an isocyanate;
- a resin selected from the group consisting of unsaturated polyesters, unsaturated polymers of vinyl esters, and unsaturated polymers of dicyclopentadiene, and combinations thereof;
- and
- a hydroxylated methacrylate monomer.
