ABSTRACT:
The present invention relates to a method for making nitrosamine-free silicone articles by treating the mixture of vinyl containing organopolysiloxane and filler with hindered phenols, a nitrosamine-free composition and a nitrosamine-free article made therefrom. A preferred nitrosamine-free molded article is a baby bottle nipple.
