    摘要： Certain hydrazodicarboxylates, namely polymers or oligomers made by reacting hydrazine with polyfunctional haloformates, especially difunctional haloformates, cyclized forms of said oligomers and condensation products of hydrocarbyl carbazates with polyfunctional, especially difunctional, haloformates are useful as chemical blowing agents for expanding gas-expandable polymeric materials. These compounds are novel.

    摘要： A blowing agent composition, comprising: (i) azodicarbonamide; (ii) zinc oxide and/or zinc carbonate; and (iii) at least one member selected from the group consisting of zinc salts of C.sub.1 -C.sub.6 organic acids, and C.sub.1 -C.sub.6 organic carboxamides characterized by a high gas evolution rate. The blowing agent composition may be used in effective amounts in formulations containing a foamable polymer to yield an efficiently gas expanded polymeric composition upon exposure to heat. Suitable C.sub.1 -C.sub.6 organic acids for said zinc salts include straight-chain carboxylic acids, and useful organic carboxamides include formamide.

    摘要： Novel blowing agents are disclosed comprising 3,3'-carbonylbis(organo carbazates). The organo group may be alkyl, cycloalkyl, aryl or aralkyl moieties. In the preferred embodiment the organo group is an alkyl group selected from the group consisting of methyl, isopropyl, secondary butyl or tertiary butyl. The blowing agents find utility in the preparation of expanded organoplastic materials such as rubbers, thermosetting resins and thermoplastic resins.
