摘要

<正> In the process of bulk photopolymerization of styrene initiated by AIBN decomposition polyvinyl benzophenone （PVB） can supply an effective cage for triplet-triplet energy transfer between PVB macromolecules and small molecules of AIBN to influence the molecular weight of polystyrene in weak magnetic field （less than 0.035T）

that was different from the case of polyvinyl naphthalene （PVN） which supplied cages for this system only in the stronger magnetic field （more than 0.2 T） studies. It was found that in the same conditions

PVN could exert more tremendous influences on the bulk photopolymerizatiou system of styrene than PVB because in the stronger magnetic field the triplet PVN had much longer life time than PVB.

Abstract

In the process of bulk photopolymerization of styrene initiated by AIBN decomposition polyvinyl benzophenone （PVB） can supply an effective cage for triplet-triplet energy transfer between PVB macromolecules and small molecules of AIBN to influence the molecular weight of polystyrene in weak magnetic field （less than 0.035T）

PVN could exert more tremendous influences on the bulk photopolymerizatiou system of styrene than PVB because in the stronger magnetic field the triplet PVN had much longer life time than PVB.
