摘要: A radiation resistant resin suitable for the manufacture of, example, disposable medical supplies comprises a semicrystalline polypropylene or propylene-ethylene and from 1500 to 5000 ppm triallyl trimellitate. The exhibits substantially no increase in melt flow rate after irradiation dosage of up 5 Mrads, may contain about 5% by weight polybutylene and/or 3000 sorbital based clarifying agent.
