摘要: There are disclosed a polyacetal composition comprising(A) 70-97% by weight of a polyacetal and(B) 30-3% by weight of a transparent polyamide elastomer represented by the general formula ##STR1## in which PA and G represent the groups specified as in the body of the text;said polyamide elastomer exhibiting a relative viscosity of at least 1.5 in m-cresol at 30.degree. C. and at a polymer concentration of 0.5 g/dl anda 1-mm thick sheet of the polyamide elastomer having a haze of not more than 75%, and streched and oriented polyacetal material using it.
