Abstract
Hydroquinone inhibits polymerization of vinyl acetate and vinyl chlori de and accelerates the polymerization of acrylonitrile and methyl meth acrylate in the presence of triisobutylboron-containing radical initia ting systems. The selective action of hydroquinone on these monomers i s caused by the different electrophility of growing macroradicals coor dinated with alkylboron. The poly(acrylonitrilic) and poly(methyl meth acrylic) radicals coordinationally linked by triisobutylboron do not e liminate the hydrogen atom from hydroquinone and exhibit high reactivi ty to benzoquinone.
