PREPARATION AND REACTIVITY OF METAL-CONTAINING MONOMERS .26. THERMAL DECAY OF COPPER DIACRYLATE

The kinetics and mechanism of thermal decay of an unsaturated copper c arboxylate, Cu(OCOCH=CH2)(2) (CuAcr(2)), have been studied. At 190-240 degrees C the rate of thermal decay can be adequately described by a set of zero and first order rate equations. The initial rate of decay, W-0, is equal to 1.7.10(17)exp[-48500/(RT)] s(-1). The decay products of CuACr(2) were analyzed by IR and mass spectroscopy as well as by o ptical microscopy. It has been established that the thermal decay of t he monomer under study is accompanied by polymerization, fragmentation , and recombination processes in the solid phase which produce polymer ic agglomerates.
