摘要： A moisture- and heat-resistant flexible polyurethane foam, which is free from lowering of the foam hardness due to moisture absorption during or after the production of the foam under a high temperature and high humidity condition and free from development of scorch during the production of the foam, can be obtained by adding an amino acid or an amino acid analogous compound to a raw material mixture, and foaming the resulting mixture.

摘要： Aldehyde functional polymers having a molecular weight of about 500 to 50,000 and containing aldehyde functional groups at both ends and/or on side chains of the molecule are produced by subjecting some of the double bonds in a high polymer containing olefinically unsaturated double bonds to ozone-decomposition by ozone-containing gas and reducing the ozone-decomposition products by means of a trivalent phosphorus compound as a reducing agent into substantially only aldehyde functional groups.

摘要： The present invention relates to a process for manufacturing a new elastomer having high elasticity, mechanical strength and processability from epoxy compounds, trimellitoyl-functional polymers and a third element. The third element is any of acid anhydride compounds having a molecular weight lower than 700, and having at least one acid anhydride group, such as maleic, phthalic, succinic, adipic, trimellitic, pyromellitic, and benzophenone tetracarboxylic anhydrides. It is, according to another aspect, an improvement of physical properties, especially tensile and tear strengths of the elastomer manufactured by reacting said first two elements according to the copending application Ser. No. 143,643, filed May 14, 1971, while keeping desirably low exothermicity and thermal contraction during the curing.
