Poly(vinyl oxazoline ester) and poly(stearyl methacrylate) were found to be good alien polymers for grafting of methyl methacrylate by suspension polymerization whereas poly(tridecyl methacrylate) was not a good backbone. Azobisisobutyronitrile was found to be an inefficient grafting initiator where azocumene that produces highly resonance and hyperconjugated stabilized dimethyl phenyl methyl radical was a superior initiator to benzoyl peroxide for grafting. Poly(stearyl methacrylate) was found to be a suitable polymeric stabilizer for nonaqueous suspension polymerizations.
