ABSTRACT:
A gas-releasing composition of a t-alkylhydrazinium salt and/or a carbonylhydrazine and at least one compound selected from free radical forming sources, metal oxides, and sulfur and/or sulfur donor compounds wherein when sulfur and/or a sulfur donor compound is used, the composition will also contain one or more members selected from sulfur accelerators, metal oxides, and amino-alcohols. This novel gas-releasing composition permits the selectively tailoring of the gas evolution of a system in order to meet a wide range of specific application areas polymer characteristics and conditions over a wide temperature range.
