Abstract
In this paper, the effect of ammonia solution as a crosslinking agent for sulphochlorinated polyethylene (SCPE) before and after being blend ed with polyvinyl chloride (PVC) is examined, by means of swelling mea surement determinations. It is seen that the higher the concentration of NH3 used, the higher the percentage of undissolved SCPE in the samp le. Moreover the present results prove that an appreciable degree of c rosslinking in the blend requires the employment of extreme conditions such as the use of fractionated SCPE and immersion of the blend sampl e for long periods in the curing media.
