Abstract
p-Hydroxymethylbenzyl chloride was found to be an effective cross-linking a
gent for polystyrene. The reaction was found to occur by Friedel-Crafts alk
ylation between the benzyl alcohol/chloride functional groups in the additi
ve and phenyl ring in polystyrene. The reaction was studied by TGA-IR to mo
nitor the evolution of hydrogen chloride and water, and the structure of th
e resultant gel was analyzed by solid state NMR and elemental analysis. The
potential application in flame-retardancy was evaluated using Cone calorim
etry. (C) 2001 Elsevier Science Ltd. All rights reserved.
