Abstract

The process of the parent Specification for polymerizing ethylenically unsaturated compounds using as catalyst organic hyponitrites wherein the organic residue contains at least one ether oxygen atom is modified in that hyponitrites are used wherein both organic residues contain one ether oxygen atom on the alpha carbon atoms and said alpha carbon atoms are attached otherwise only to carbon atoms. The hyponitrites are preferably of formula. ROCR1R11ON = NOCR1R11OR wherein R, R1 and R11 stand for organic radicals and R and R1 or R1 and R11 may be linked together so as to form, with the alpha carbon atom, a ring. Specified hyponitrites are bis (1-methoxy - 1 - methylethyl), bis(1 - ethoxy - 1-methylethyl), bis(1 - nonyloxy - 1 - methylethyl), bis(1 - methoxy - cyclopropan - 1 - yl), bis(1 - methoxycyclobutan - 1 - yl), bis(1-methoxycyclopentan - 1 - yl), bis(2 - methyltetrahydrofuran - 2 - yl), bis(1 - methoxy - 1-methylisobutan - 1 - yl), bis(1 - methoxy - 1-methylneopentan - 1 - yl), bis(1 - methoxy - 2,2, 4,4 - tetramethylcyclobutan - 1 - yl), bis(1-methoxy - 2 - carbomethoxycyclobutan - 1 - yl), bis)1 - methoxy - 2,5 - dimethylcyclopentan - 1-yl), bis(1 - methoxy - 1 - cyclohexylethyl) and bis(1 - methoxy - 1 - methyl - 2 - carbethoxyethyl) hyponitrites. The polymerization of vinyl acetate, ethylene, acrylonitrile and methyl methacrylate is exemplified.
