Abstract

An attempt has been made to demonstrate the applicability of poly(styrene peroxide) (PSP) as a curative in coating and molding compositions and to compare it with a conventional curative benzoyl peroxide $(Bz_2O_2)$. A typical coating formulation leads to better adhesion on aluminium and glass surfaces with PSP as curative than with $Bz_2O_2$. Similarly, a typical molding formulation, prepolymerized and cured with PSP under compression at 90°C, resulted in a colourless, defect-free molding, having better impact and tensile strengths than when using the conventional curative $Bz_2O_2$, which afforded a brown coloured, brittle product.
