Procedure

A high pressure autoclave was charged with 0.11 moles of isopropenylphosphonic acid and 0.132 moles of diisobutylene in ethylene glycol dimethyl ether. The components were reacted for 4 hours at 80° to 82° C. Benzoyl peroxide was used as the polymer initiator. 13C and 31P nuclear magnetic resonance spectra indicated approximately 10 to 30% incorporation of diisobutylene into the polymer reaction product.
