Polystyrene is very difficult to cross-link by electron beam radiation or by peroxide without destroying its properties. As a result, applications have not been developed. The methyl groups of poly-PMS, by contrast, provide susceptible positions for such a reaction. PMS polymers can be cross-linked effectively by electron-beam radiation. This unique property of tpoly-PMS could open several new markets. Crosslinking turns a PMS-based thermoplastic into a thermoset resin, significantly improving its grease resistance and flammability behavior. 

This explains the predominance of radiation-chemical reactions as a means of initiating crosslinking in thermoplastic materials. In principle the effect can be induced by electromagnetic waves such as X-rays or gamma rays or by corpuscular radiation (beta rays) such as accelerated electron beams, for example. The differences between...
