Gas-releasing composition for tailoring gas evolution of system
First Claim
1. A gas-generating composition consisting essentially of a t-alkylhydrazinium salt and/or carbonylhydrazine and at least one compound selected from free radical forming sources;
- metal oxides selected from ZnO, PbO, Pb3 O4 or MgO; and
sulfur 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.

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.
