FREMGANGSMAATE FOR REGULERING AV POLYMERISASJONEN AV VINYLMONOMERER SAMT PARTIKKELFORMIG VINYLHALOGENIDHARPIKSMATERIALE

It has been found that substituted hydroquinones function as a shortstop agent in the polymerization of vinyl monomers. The substituted hydroquinones have the formula: wherein R' = and R'' = wherein p is 1 or 2 and q is 0 or 1; provided that p+q = 1 or 2. The groups R1, R2, R3, R4, Z...

description	It has been found that substituted hydroquinones function as a shortstop agent in the polymerization of vinyl monomers. The substituted hydroquinones have the formula: wherein R' = and R'' = wherein p is 1 or 2 and q is 0 or 1; provided that p+q = 1 or 2. The groups R1, R2, R3, R4, Z and W are defined hereafter. The compounds 2,5-di-t-amylhydroquinone and 2,5-di-t-butylhydroquinone are particularly desirable as shortstop agents in the polymerization of vinyl chloride. These hydroquinones also function as stabilizers for the resin and finished articles made therefrom.
