Abstract
Abstract There are disclosed thermoplastic and thermosetting polymers which incorporate tungsten and/or molybdenum metal atoms. The metal atoms are incorporated into the polymer by reacting a monomer or polymer containing at least one free carboxyl group with a reaction product of tungsten or molybdenum and pyrrolidine.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
40 words

Claim 2
Dependent Claim
40 words
A thermosetting polymer obtained by reacting an epoxy resin with the reaction product of either a saturated or an ethylenically unsaturated dicarboxylic acid and a metal complex which is a reaction product of tungsten carbonyl and/or molybdenum carbonyl with pyrrolidine.
Claim 3
Dependent Claim
18 words
A thermosetting polymer as defined in claim 1 wherein said dicarboxylic acid is an ethylenically unsaturated dicarboxylic acid.
Claim 4
Dependent Claim
22 words
A thermosetting polymer as defined in claim 2 wherein said epoxy resin is obtained by the reaction of Bisphenol A and epichlorohydin.
Claim 5
Dependent Claim
65 words
A thermosetting polymer obtained by reacting an epoxy resin with a thermoplastic polymer containing tungsten and/or molybdenum metal atoms chemically bonded in the polymer chain, said thermoplastic polymer comprising the reaction product of (1) a metal complex which is a reaction product of tungsten carbonyl and/or molybdenum carbonyl with pyrrolidine and (2) a condensation product of a dicarboxylic acid or anhydride and a polyhydric alcohol.
Claim 6
Dependent Claim
65 words
A thermosetting polymer obtained by reacting an epoxy resin with a thermoplastic polymer containing tungsten and/or molybdenum metal atoms chemically bonded in the polymer chain, said thermoplastic polymer comprising the reaction product of (1) a metal complex which is a reaction product of tungsten carbonyl and/or molybdenum carbonyl with pyrrolidine and (2) a condensation product of a dicarboxylic acid or anhydride and a polyhydric alcohol.
Claim 7
Dependent Claim
22 words
A thermosetting polymer as defined in claim 4 wherein said epoxy resin is obtained by the reaction of Bisphenol A and epichlorohydrin.
