Jp. Montheard et al., THERMAL CROSS-LINKING REACTION OF A STYRENIC COPOLYMER FOR NONLINEAR OPTICS, Journal of macromolecular science. Pure and applied chemistry, A31, 1994, pp. 471-480
In order to prepare thin film of crosslinked copolymer for nonlinear o
ptics, the copolymerization of styrene and 4 ethenyl alpha acetoxystyr
ene has been studied. Soluble copolymers have been obtained and the va
riations of their molecular masses show that a partial thermal crossli
nking reaction occurs. This property has been used to prepare thin fil
ms of terpolymer of styrene, dye for nonlinear optics and of 4 ethenyl
alpha acetoxystyrene, which have been crosslinked after heating in an
oven.
