摘要：

The influence of already formed polymer chains on the photopolymerization of the diacetylene crystal pTS has been studied using the holographic method. It is shown that, for wavelengths between 340 and 400 nm, photopolymerization occurs and is faster in more polymerized regions. This sensitized process does not involve polymer excited states, but most probably the monomer triplet. It is a two-quantum process. It is proposed that this "sensitization" is in fact due to the elastic effects of polymer chains into the surrounding monomer matrix. © 1990.
