Fluorinated surfactants: synthesis properties applications,by Erik Kissa. Marcel Dekker Inc., New York, 1994, pp. vii + 469, price US$165.00. ISBN 0-8247-9011-1

The photocoloration of a novel spirooxazine, 1-[β-(4-trifluoromethyl benzoyloxy)ethyl]-3,3-dimethyl-spiro[indoline-2,3′-[3H]-naphtho[2,1-b]-1,4-oxazine] (SO), doped in different polymer films and fibers was studied. The results show that photocoloration increased with increasing concentration of spirooxazine in polymer films. The photocoloration rate of spirooxazine in PMMA is faster than that in PS due to the polarity of the polymer films. A general model for the kinetics of photocoloration of spirooxazine in polymer films is proposed. The results also show that the photocoloration rate of spirooxazine in PET is faster than that in Nylon-6 due to the crystallinity of the polymer fibers.
