Abstract
A composition and adhesive film of a thermosetting resin and a terpolymer of an α-olefin, carbon monoxide and an ethylenically unsaturated carboxylic ester monomer, wherein the melt temperature of the terpolymer is less than the set temperature of the thermosetting resin. The film may be applied to a substrate to provide for an adhesive backing. The film may also be utilized to adhesively bond first and second substrates together.
Claims23
A composition comprising:
- (a) a terpolymer of an -olefin, carbon monoxide and an ethylenically unsaturated carboxylic ester monomer;
- and
- (b) a thermosetting resin;
- wherein the melt temperature of the terpolymer is less than the set temperature of the thermosetting resin.
A film comprising:
- (a) a terpolymer of an -olefin, carbon monoxide and an ethylenically unsaturated carboxylic ester monomer;
- and
- (b) a thermosetting resin;
- wherein the melt temperature of the terpolymer is less than the set temperature of the thermosetting resin.
A method of making a film, the method comprising:
- (a) heating a mixture of a thermosetting resin and a terpolymer of an -olefin, carbon monoxide and an ethylenically unsaturated carboxylic ester monomer, to a temperature that is above the melt temperature of the terpolymer and below the set temperature of the thermosetting resin, wherein the melt temperature of the terpolymer is less than the set temperature of the thermosetting resin;
- (b) forming the heated mixture into a film;
- and
- (c) cooling the film to below the melting temperature of the terpolymer.
A product comprising:
- (a) a substrate;
- (b) an adhesive film affixed to the substrate, wherein the film comprises a thermosetting resin and a terpolymer of an -olefin, carbon monoxide and an ethylenically unsaturated carboxylic ester monomer, wherein the melt temperature of the terpolymer is less than the set temperature of the thermosetting resin.
A method of making a product, the method comprising:
- providing a substrate;
- and affixing to said substrate, an adhesive film comprising:
- a thermosetting resin;
- and
- a terpolymer of an -olefin, carbon monoxide and an ethylenically unsaturated carboxylic ester monomer, wherein the melt temperature of the terpolymer is less than the set temperature of the thermosetting resin.
A product comprising:
- (a) a first substrate;
- (b) a second substrate;
- and
- (b) an adhesive film positioned between the first and second substrates and affixed to each, wherein the film comprises a thermosetting resin and a terpolymer of -olefin, carbon monoxide and an ethylenically unsaturated carboxylic ester monomer, wherein the melt temperature of the terpolymer is less than the set temperature of the thermosetting resin.
A method of making a product, the method comprising:
- positioning between a first substrate and a second substrate an adhesive film;
- and affixing to each substrate, said film comprising:
- a thermosetting resin;
- and
- a terpolymer of an -olefin, carbon monoxide and an ethylenically unsaturated carboxylic ester monomer, wherein the melt temperature of the terpolymer is less than the set temperature of the thermosetting resin.
