ABSTRACT:
Novel loop polymers having a polymeric backbone and a plurality of olefinic groups which have been converted to closed loops by reaction with difunctional organic compounds reactive with said olefinic groups, said olefinic groups from which the loops are formed may either be present within the backbone and/or pendent from the polymeric backbone. The loop polymers may also have hydroxy or carboxy groups which can be capped with diisocyanates or epoxies, respectively.
