Tn. Konstantinova et Ik. Grabchev, ON THE COPOLYMERIZATION OF STYRENE AND ACRYLONITRILE WITH 1,8-NAPHTHALIMIDE DERIVATIVES (OPTICAL BRIGHTENING AGENTS), Polymer international, 43(1), 1997, pp. 39-44
The polymerization of styrene and acrylonitrile in the presence of two
unsaturated optical brightening agents (OBs), 1,8-naphthalimide deriv
atives, has been investigated. It was found that the monomeric optical
brighteners took part in the polymerization and were covalently bound
in the polymer chain. The influence of the monomeric OBs on the rate
of the process and on some of the properties of the copolymers thus ob
tained, such as molecular weight and thermostability, was established.
