Abstract
Official abstract text for this publication.
The gas generating agent of the present invention comprises an oxalic acid salt of an aminoguanidine compound represented by general formula (1) below.
First claim
Opening claim text (preview).
The invention claimed is: 1. A foamable composition comprising: a gas generating agent including an oxalic acid salt of an aminoguanidine compound represented by general formula (1) below wherein X and Y are each independently a hydrogen atom or an amino group; and a material to be foamed. 2. The foamable composition according to claim 1 , wherein in the oxalic acid salt of the aminoguanidine compound, a molar ratio of the aminoguanidine compound to oxalic acid (aminoguanidine compound:oxalic acid) is in a range of 1:1 to 2:1. 3. The foamable composition according to claim 1 , wherein the aminoguanidine compound is aminoguanidine. 4. The foamable composition according to claim 1 , wherein the gas generating agent is a microcapsule-based agent. 5. The foamable composition according to claim 1 , wherein the material to be foamed is a thermoplastic resin and/or a rubber. 6. A method for producing a foam, comprising a step of heating the foamable composition according to claim 1 . 7. A foam, wherein the foam is obtained by foaming the foamable composition according to claim 1 .
