| Abstract: | A method of preparing the foam plastic of polyvinyl formal （PVF） using starch as pore forming agent. The effects of type and content of polyvinyl alcohol （PVA）, type and content of starch, content of formaldehyde and sulfuric acid on the properties of PVF foam plastic were studied, and foam morphology was also analyzed. The results showed that the resulting foam plastics possess different density, hardness, and elasticities due to their different components. This foam plastic has good market prospect as a good absorbent material |
