摘要
Abstract
Effects of the different dosage of nucleator on crystallizing and mechanical property of POM were stud-ied by means of differential scanning calorimetry,polarizing microscopy and universal material testing machine. The results indicated that nucleators effectively decreased spherocrystal size of POM. And the nucleators could improve crystallization temperature and notched impact strength. When the addition amount was 0. 8%,it made crystalliza-tion peak temperature of POM increased from 139. 2℃ to 143. 3℃, spherocrystal size decreased to 1/2 of POM without nucleator,and notched impact strength was improved from 5. 5kJ·m-2 to 6. 1kJ·m-2.关键词
