A polymer comprising a carbon-carbon backbone chain and at least one N-(substituted oxalyl)carbamoyl group of the formula: --CO--NH--CO--CO--OR wherein R is a hydrocarbon group as a side chain attached to said backbone chain.
摘要:
A physical property-improving reagent which comprises an alkenoylcarbamate compound of the formula: ##STR1## wherein R is a hydrogen atom or a lower alkyl group, X is an oxygen atom (--O--), a sulfur atom (--S--) or a substituted or unsubstituted imino group (--NR'--), R' being a hydrogen atom or a lower alkyl group, and Y is the residue of an active hydrogen atom-containing compound excluding --X--H therefrom dissolved in an organic solvent having a solubility parameter of not less than 8, which can impart excellent physical properties to a polymer produced with the same.
