The synthesis of intramolecularly crosslinked polystyrene molecules has bee nachieved by controlled chlormethylation of anionic polystyrene. The chlormethyl groups were reacted with n-butylamine and the secondary amine derivative thus produced was crosslinked by reaction with a diisocyanate in dilute solution. Samples were prepared containing a selected number of crosslinks in the range 5 to 150 per polymer molecule. The materials were completely soluble. The number of crosslinks in each sample was determined by quantitative infrared studies.
