Abstract

The solid system of n-vinylsuccinimide with benzoquinone is characterized by the formation of an eutectic. Up to the composition of the eutectic, the rate of the solid-state polymerization decreases regularly with an increase in the BQ concentration. Beyond the eutectic composition the polymerization rate is constant even at very high concentrations of benzoquinone. This is explained by the development of a system (as shown by the X-ray patterns) with maximum heterogeneous interfaces and of a very fine structure in which the inhibitor interfaces and the inhibitor molecules are able to exert their inhibiting action on the surfaces of the monomer crystals. The phase diagram of the n-vinylsuccinimide -phthalic anhydride system shows a eutectic also. In this case, polymerization rate increases with increasing phthalic anhydride concentration, and no energy transfer effect can be observed in the heterogeneous system containing an aromatic component.
