heal.abstract	Styrene-ethylene-butylene ABA triblock copolymer was modified via a novel post-polymerization reaction system, employing available styrene units and a bifunctional chloromethylated agent. The reaction was carried out in solution using a system based on carbon tetrachloride-cyclohexane mixtures and TiCl4 catalysis. Using u.v. spectroscopy, it is demonstrated that the styrene units of the copolymer are reactive under the applied conditions. A series of products having various degrees of crosslinking was studied in order to characterize their swelling behaviour within a range of organic solvents. Data concerning the kinetics of the reaction, the porosity and the morphology of the final networks were also obtained.	en
