Abstract
There are disclosed polymers containing tungsten chemically bonded in the polymer chain. The polymers are obtained by reacting 2-furanacrylic acid or 2-furoic acid with the reaction product of tungsten carbonyl with pyrrolidine. These polymers are useful as multi-cycle reimpregnation resins.
Claims6
The thermoplastic/thermosetting reaction product of (1) 2-furanacrylic acid or 2-furoic acid and (2) a metal complex which is a reaction product of tungsten carbonyl with pyrrolidine, said product being a multi-cycle reimpregnation polymer.
