摘要： Described are processes for preparing brominated diphenylalkane products which are far whiter than prior known brominated diphenylalkane products. The resultant white brominated diphenylalkane products also form a part of the present invention, as do formulations incorporating the white brominated diphenylalkane products, and articles prepared therefrom.

摘要： A process for the production of cellular products which comprises incorporating a blowing agent into rubber or a thermoplastic material uses as the blowing agent a tetrazole compound represented by the formula: ##STR1## in which R represents an alkyl, cycloalkyl, hydroxyalkyl, polyhydroxyalkyl, aryl, alkylaryl, aralkylene, alkenyl, alkenylaryl or alkenylaralkylene group.The novel blowing agents of the present invention include compounds which are liquids which may be directly incorporated into the molten rubber or thermoplastic material. The blowing agents of this invention are especially useful, as indicated, with polymers and copolymers that have high processing temperatures as they minimize polymer degradation and provide products with increased impact strengths.
