    摘要： The present invention provides novel polyacylurethane, and a process for producing the same. More specifically, the present invention provides polyacylurethane having a molecular weight of 500 to 50,000, wherein a main chain of said polyacylurethane is substantially composed of a repeating unit of the formula:

    wherein R₁ represents an alkylene group or an alkenylene group having a molecular weight of 28 to 30,000, which may contain an alicyclic group, an aromatic group and/or an oxygen atom; and R₂ represents an alkylene group, an arylene group or an alkenylene group having 1 to 8 carbon atoms.

    摘要： A method for handling and stabilizing a (2-alkyl)acryloyl isocyanate represented by formula (1) is disclosed, which comprises the steps of:
       reacting an azomethine compound represented by formula (2) with the (2-alkyl)acryloyl isocyanate to obtain a reaction product and
       dissolving the reaction product into a solvent to regenerate the (2-alkyl)acryloyl isocyanate;

    wherein R¹ represents a hydrogen atom or a lower alkyl group,

    wherein
    R² represents an alkyl group, a cycloalkyl group, an aralkyl group, an alkenyl group, or an alkynyl group, and
    R³ and R⁴ each represents a hydrogen atom or a group which does not cause tautomerism with C=N in the formula, provided that at least one of R³ and R⁴ is not a hydrogen atom, and further a method for producing a (2-alkyl)acryloyl isocyanate is disclosed, which comprises the step of:
       preparing a heterocyclic compound represented by formula (3) and
       dissolving the heterocyclic compound into a solvent;

    wherein R¹ represents a hydrogen atom or a lower alkyl group,

    wherein
    R⁵ represents a hydrogen atom or a lower alkyl group,
    R⁶ represents an alkyl group, a cycloalkyl group, an aralkyl group, an alkenyl group, or an alkynyl group, and
    R⁷ and R⁸ each represents a hydrogen atom or a group in which a carbon atom located in the α-position to carbon atoms constituting a heterocyclic ring does not have a hydrogen atom, provided that at least one of R⁷ and R⁸ is not a hydrogen atom.
