摘要
用激光小角散射法（SALS）研究了多种聚甲醛的成核添加剂．结果表明：由弹性体和滑石粉组成的复合成核添加剂，能够减小结晶的尺寸．共聚甲醛的成型收缩率从3．3％降至2．0％．
Several nucleating additive agents of polyoxymethylene were studied by means of laser small-angle light scattering (SALS). It was found that complex nucleation agent of elastomer (S) and tale can reduce the crystal size. The shrinkage of dioxolane - formdehyde polyemer was decreased from 3. 3% to 2. 0%.
