## Abstract Divalent metal salts of ethylene glycol–methacrylate–phthalate (EMP) were prepared by the reaction of EMP and divalent metal ions in aqueous solution. The divalent metal salts obtained, except for the Pb salt, have melting points which decrease in the order of Ca > Ba > Mg > Zn > Cd sal
Monomer reactivity ratios have been determined from the copolyrnerization of methyl methacrylate with (a) t4C-diethyl maleate and (b) t4C-diethyl fumarate initiated with 1.1' azo-bisisobutyronitrile at 60 °. Values of 354+ 57 and 0 for the methyl methacrylate--diethyl maleate system are very differe
