Abstract: Prepn. of homopolymers of styrene and its derivs. as well as copolymers of these monomers with each other or with =50 wt % of other anionic copolymerisable unsatd. cpds. is effected by polymsn. in a solvent in the presence of alkali and using isophthalic acid to terminate the polymsn. The polymers are transparent and no discolouration occurs when working up at high temps.
