A novel filler free silicone rubber biomaterial. II. Radiation chemical and physical evaluation.

Abstract

Hexamethylcyclotrisiloxane was polymerized at 60 degrees C by gamma radiation to yield filler free silicone rubber (FFSR). The G (crosslinking) value of 23.5 was found for the FFSR polymerized for 4 hours, compared to about 2 for the pure polydimethylsiloxane (PDMS). The sol fractions for both FFSR and cross-linked PDMS varied between 5-7%. The FFSR and the… (More)
