Abstract
The triplet-triplet annihilation of mass fractionated PVCA (M = 3.6.10 (3)-1.4.10(6)) in toluene glasses was studied by phosphorescence, for glasses of PVCA and P2VN (order of M = 10(6)) in MTHF the intensity of phosphorescence and delayed fluorescence were studied as a function o f the excitation intensity. A survey of T-T annihilation in solid solu tions of aromatic polymers is given and requirements for a theory expl aining low dimensional energy transport and exciton-exciton annihilati on art pointed out.
