Abstract

Addition prods. of functional trihalogenomethyl cpds. or polymers, copolymers or terpolymers having C=C bonds are prepd. by reacting a cpd. CX3Z (where X is Cl, Br or I, and Z is a gp. having a polarity allowing or promoting homolytic cleavage of the C-X bond) with the polymer at moderate temp. (pref. 50-140 degrees C) and under pressure, in presence of a catalyst of formula Cl2Ru(PPh3)3 (I) and opt. a co-catalyst comprising OH gp-contg. organic cpds. or water. Reaction is effected in an inert solvent for the polymer and the catalyst. The process gives good yields and a low degree of secondary reactions. The prods. can be added either as intermediates or as such to high molecular wt. polymers to impart improved stability and in some case flame resistance. The prods. can also be esterified, hydrolysed, amidified, vulcanised or grafted to give a variety of prods.
