The nature of trapping centers in amorphous biphenyl-containing polymer.
Study of optical properties of methyl methacrylate and 4-vinylbiphenyl copolymers in a rigid amorphous polymer allowed establishing the non-excimer nature of energy traps in a polymer chain. These traps are probably related to possibility of collective states formed by macromolecule's chromophore groups. The shortening of the trap states decay time in 4-vinylbiphenyl homopolymer comparing to copolymer is observed.
