    • A rubber composition consisting essentially of 5-99 parts by weight of a thermosetting resin and 94-1 parts by weight of one of the following functional rubber-like copolymers (I) to (III) having a Mooney viscosity ML.sub.1+4.sup.100 of 20-120:(I) a functional rubber-like copolymer consisting of 1-20% by weight of a monomer having epoxy groups, hydroxyl groups or amino groups, 15-50% by weight of acrylonitrile and 40-80% by weight of butadiene and/or isoprene as monomer units constituting the polymer,(II) a functional rubber-like copolymer consisting of 1-20% by weight of a monomer having epoxy groups, hydroxyl groups or amino groups, 40-99% by weight of an alkyl (meth)acrylate and/or an alkoxyalkyl (meth)acrylate and 0-30% by weight of monomers copolymerizable therewith other than butadiene and isoprene, as the monomer units constituting the polymer, and(III) a functional rubber-like copolymer consisting of 1-20% by weight of a monomer having epoxy groups, hydroxyl groups or amino groups, 15-50% by weight of acrylonitrile, 20-60% by weight of butadiene and/or isoprene and 5-65% by weight of an alkyl (meth)acrylate and/or an alkoxy (meth)acrylate as the monomer units constituting the polymer.Said functional rubber copolymer may include 10% by weight or less of a polyfunctional monomer as a monomer unit constituting the polymer. In this case, the ratio of the thermosetting resin to the functional rubber-like copolymer is 50-99 parts by weight of the former to 1-50 parts by weight of the latter.
    • 基本上由5-99重量份的热固性树脂和94-1重量份具有门尼粘度ML1 + 4100为20〜20的功能性橡胶状共聚物(I)〜(III)之一组成的橡胶组合物, 120:(I)由1-20重量%的具有环氧基,羟基或氨基的单体,15-50重量%的丙烯腈和40-80重量%的丁二烯组成的功能性橡胶状共聚物,以及 /或异戊二烯作为构成聚合物的单体单元,(II)由1-20重量%的具有环氧基,羟基或氨基的单体组成的官能橡胶状共聚物,40-99重量%的烷基( (甲基)丙烯酸酯和/或(甲基)丙烯酸烷氧基烷基酯和0-30重量%的除丁二烯和异戊二烯之外可共聚的单体作为构成聚合物的单体单元,和(III)由1 -20重量%的具有环氧基,羟基或氨基的单体,15 -50重量%的丙烯腈,20-60重量%的丁二烯和/或异戊二烯和5-65重量%的(甲基)丙烯酸烷基酯和/或烷氧基(甲基)丙烯酸酯作为构成聚合物的单体单元 。 所述功能橡胶共聚物可以包含10重量%以下的作为构成聚合物的单体单元的多官能单体。 在这种情况下,热固性树脂与官能橡胶状共聚物的比例为前者的50-99重量份,后者的1-50重量份。
