    • An objective of the present invention is to provide an unsaturated nitrile-conjugated diene-typed rubber capable of giving a vulcanized rubber which exhibits is well-balanced in terms of the mechanical strength, the oil resistance and the like, as well as a process for the production of the same, and a rubber composition which is containing such rubber and exhibits an excellent processability as well as a process for the production of the same. The unsaturated nitrile-conjugated diene-typed rubber in the invention is produced by polymerizing using certain amounts of an olefinically unsaturated nitrile monomer such as acrylonitrile and a conjugated diene monomer such as butadiene at first, and continuing by supplying a remainder of the monomers at a certain ratio continuously or stepwise to proceed the polymerization. The unsaturated nitrile-conjugated diene-typed rubber is constituted 55 to 80wt% of an olefinically unsaturated nitrile monomer unit as a repeating unit and 20 to 45wt% of a conjugated diene monomer unit as a repeating unit based on 100wt% of total of the monomer units. Glass transition temperature is -15 to 30°C and the extrapolated temperature of the termination of the glass transition is preferably 70°C or less.

    • An acrylonitrile solution of maleimide manifesting transparency, precluding coloration and opacification during the course of handling, and excelling in stability, a method for the preparation of the acrylonitrile solution, and an acrylonitrile based copolymer obtained by using the acrylonitrile solution are provided.
      The acrylonitrile solution of maleimide is such that, when it is subjected to a forced coloration test, the differences Δ L, Δa, and Δb values (invariably as absolute values) each between L, a, and b values before and after the test are respectively not more than 5, not more than 5, and not more than 10. The acrylonitrile solution of maleimide is prepared by lowering the water content in the acrylonitrile solution to a level of not more than 0.1% by weight, or causing the acrylonitrile solution to permit coexistence therein of at least one member selected from the group consisting of alkyl-substituted hydroxybenzenes and hindered phenols and at least one member selected from the group consisting of phosphorous esters, phosphoric esters, phosphine, and phosphoric acid amides, or lowering the water content in the acrylonitrile solution to a level of not more than 0.3% by weight and causing the acrylonitrile solution to permit coexistence therein of at least one member selected from the group consisting of alkyl-substituted hydroxybenzenes, hindered phenols, phosphorous esters, phosphoric esters, phosphine, and phosphoric acid amides.
