| Abstract: | Organic phosphoric acid ester nucleators 611,612,613,NA-11 and 0629C-3 were mixed in 2% with polypropylene respectively.The structure of brittle failure surface of the sample was observed.The change of mechanical performance on the sample around mixing nucleator into polypropylene was measured,and the causes of the change were analyzed.The performance of the sample that mixed nucleator 0629C-3 in 1% was compared with that in 2%. |
