Summary

Carefully selected primary components, viz., PVC and suitable plasticizers, allowed to prepare a plasticized PVC that resisted 35-kGy doses ofhigh-frequency radiation and retained the biochemical and chemical properties on accelerated aging intended to simulate a two-year's long storage at ambient temperature. Medical-grade suspension PVC, >99.8% puredi-(2-diethylhexyl)phthalate and equally pure tris-(2-ethylhexyl)trimellitate used as plasticizers, and stearoyl benzoyl methane and mercaptotin ester used as additional stabilizers, proved to be the appropriate components. Some special stabilizers reported to have been screening ionizing radiation proved in effective when used to prevent degradation in the plasticized PVC.
