ムの開環重合によって得られるものである。Here, PA12 used in the present invention is 1:NH(
It is expressed by the formula CH2), CO-1, and is obtained by ring-opening polymerization of ω laurolactam.
また本発明において用いられるＰＰとはホモポリマー、
コポリマーのいずれに限定されるものでよないか、立体
規則性を持つ結晶化度か高い高結晶性ＰＰの使用か特に
好ましい。In addition, PP used in the present invention is a homopolymer,
Although it is not limited to any copolymer, it is particularly preferred to use highly crystalline PP with stereoregularity or high crystallinity.
また相溶化剤である変性ポリオレフィンはアクリル酸や
