摘要

用多组分熔融接枝的方法将甲基丙烯酸缩水甘油酯 (GMA)和苯乙烯(St)共同接枝到聚丙烯 (PP)上

制得具有较高GMA接枝率的多单体接枝聚丙烯

PP-g-(GMA-co-St).将PP-g-(GMA-co-St)与尼龙6 (PA6)进行共混

利用扫描电镜 (SEM)

差示扫描量热计 (DSC)和广角X射线衍射 (WAXD)对共混物的形态和结晶进行了研究 .在共混过程中

PP-g-(GMA-co-St)与PA6反应原位生成了PP-g-PA6

有效改善了共混物的相容性

分散相尺寸明显减小.在PP-g-(GMA-co-St)/PA6为3/7的体系中

PP-g-(GMA-co-St)出现分级结晶现象

其在较低温度下的结晶属于均相成核结晶.在PP-g-(GMA-co-St) PA6为7/3的体系中

由于PA6相分散细微

在通常结晶温度下不结晶

而是在低温下均相成核与PP-g-(GMA-co-St)同时结晶 .WAXD证实体系中接枝PP

PA6为分别结晶

无共晶或新的晶型产生.

Abstract

The Glycidyl Methacrylate(GMA)／Styrene(St) multi-monomer melt-grafted polypropylene

PP-g-(GMA-co-St)

which has a high grafting degree of GMA

was blended with Polyamide 6 (PA6)．The morphologies and crystallization of the blends were investigated by means of SEM

DSC and WAXD．PP-g-PA6

which formed during the reactive blending process

improved greatly the compatibility of the blends and reduced the size of the dispersed phase dramatically．In the PP-g-(GMA-co-St)／PA6=3／7 blend

the fractionated crystallization of PP-g-(GMA-co-St) was observed．The crystallization of PP-g-(GMA-co-St) at the lower temperature should be assigned to homogeneous nucleation. In the 7／3 blend

due to the fine dispersion of PA6 phase

PA6 did not crystallize at its normal crystallization temperature (Tc)

but crystallized in the mode of homogeneous nucleation at a lower Tc simultaneously with the crystallization of PP-g-(GMA-co-St)．The WAXD showed PP-g-(GMA-co-St) and PA6 crystallized separately and no new crystalline forms formed in the blends．
