PURPOSE:To provide the subject composition having good thermal melt- flowability and thermal moldability even in the case of a high reduced viscosity and useful for films, etc., by homogeneously dispersing the fine particles of a high nitrile copolymer in a matrix of low nitrile copolymer. CONSTITUTION:The objective composition comprises (A) a polymer matrix of low nitrile copolymer and (B) a high nitrile copolymer substantially homogeneously dispersed in the polymer matrix A, the matrix A comprising (i) polymer units of formula I (R<1> is H, methyl), (ii) polymer units of formula II (R<2> is H, methyl; R<3> is phenyl) and (iii) polymer units of formula III (R<4> is methyl; R<5> is 1-6C alkyl), the amounts of components i, ii, and iii being 50-85wt.%, 15-40wt.% and 0-10wt.%, respectively, based on the total amount of the components i and ii or on the total amount of the components i, ii, and iii, and the component B comprising the component i or the components i and iii, the amount of the component i being at least 86% based on the total amount of the components. |
