EPDM的音标

Different contents of EPDM degraded PP/ EPDM blends are capable of crystallization, crystallization formation of spherulites is not very perfect, spherulite structure is destroyed by different level, in EPDM to30wt% spherulitic structure is destroyed serious, crystallization is not completely.

不同EPDM含量的降解PP/EPDM共混物都能够结晶，都形成球晶，只是结晶不是很完善，球晶结构受到不同程度破坏，在EPDM达到30wt%时球晶结构破坏严重，结晶不完全。

A polystyrene ( PS)/ EPDM blend formed in situ by Friedel-Crafts alkylation in melt state was developed. The effects of the type and addition level of Lewis acid and the temperature and time of mixing on the properties of blend were investigated.

在熔融状态下，利用Friedel-Crafts烷基化反应原位生成聚苯乙烯（PS）/EPDM共混物，考察路易斯酸品种、用量、混炼温度和混炼时间等对共混物性能的影响。

And at the same time the Shore A hardness of EPDM vulcanizate increased gradually and its tensile strength and elongation at break increased at first, and then decreased.

随着Zn（MAA）2用量的增大，EPDM硫化胶的邵尔A型硬度逐渐增大，拉伸强度和扯断伸长率都是先升高再下降。
