The reasons of the presence of hydrolyzable chlorine bonded in different ways to an epoxy resin molecule were discussed and the main methods of its determination described. Using as examples of diglycidyl ether of hexanediol and triglycidyl ether of trihydroxymethylpropane [including also addition of 3-chIoropropanol-l and di(l-chloropropyl-2) ether as model compounds] the usefulness of three methods of the determination of hydrolyzable chlorine, namely PN, DOW and ISO methods, was investigated. It was stated that the DOW and ISO methods determine exclusively 1,2-chlorohydrine chlorine, whereas the PN methods determines total content of 1,2- and 1,3-chlorohydrine chlorine and about 65–85% chlorine present in isolated chloromethyl groups.
