Influence of salts of metals on size of molecular weight of poly(methyl)methacrylate

Influence of salts s-, p- and f-metals, a nature of initiators and temperature of polymerization on size of molecular weight(MM) of poly(methyl)methacrylate(PMMA) allocated from composites is investigated. It is found, that molecular weight of poly(methyl) methacrylate decreases according to a line of modifiers: lithium(I)-plymbum(II)-europium(III). Dependences of size of molecular weight on concentration of modifiers are given, influence of a nature of cations and temperatures of polymerization of samples on a course of concentration curves is revealed.
