摘要

Abstract

Polypropylene (PP)/polybutene-1 (PB) alloys within reactor were prepared by MgCl

-supported Ziegler-Natta catalyst with sequential two-stage polymerization technology. First

propylene homo-polymerizations were carried out to form isotactic polypropylene (

PP) particles containing active catalyst. Then

butene-1 was subsequently polymerized to form polybutene-1 phase inside the

PP particles. Finally

PP/PB alloys with spherical shape and adjustable PB content were synthesized. The catalytic activity and catalytic stereospecificity of the Z-N catalyst in the two-stage polymerization process are discussed. The composition and physical properties of the PP alloys were characterized by FT-IR

C-NMR

SEM

DSC and XRD. It was found that the in-reactor PP alloys are mainly composed of PP and PB with a little amount of poly(butene-

-propylene) random copolymers and poly(butene-

block

-propylene) block copolymers. SEM measurements verified that the PB phases with size in the range of 300-400 nm dispersed in the PP matrix uniformly. The incorporation of PB upon the PP matrix affects the properties of final products greatly.
