Abstract

Abstract: A series glass fiber reforced and flame retardant PBT/PET alloy engineering plastics were prepared. The crystallization of alloy was studied. Nucleation master-batches Nu-2 were used in alloy to increase crystallization. The result is that: PBT/PET alloy amorphous phase is compatibility, while crystal region is phase separation. PET blocks the crystallization of PBT. The more PET added the lower crystallization speed. Nucleation master-batches Nu-2 is a kind of good nucleation-accelerator. It not only accelerates the crystallization of PET but also control the transesterification of alloy. At the same time, the mechanical properties are close to that of neat PBT engineering plastics.

Key words: poly(ethylene terephthalate), poly(butylene terephthalate), alloy, nucleating master batch, crystallization property, mechanical property
