THE STUDY ON POLYMER BLENDS OF POLYPROPYLENE WITH POLYESTER-POLYETHER MULTIBLOCK COPOLYMERS
The polymer blends of polypropylene with polyester-polyether multiblock copolymers has been shown to be a micro-phase composite and the mechanical Properties were found to be related to the structures of soft polyether segments. The DSC and polarizing microscopy showed that the degree of crystallinity and the spherulite size of polypropylene in the blends decreased with increasing content of polyester-polyether block copolymer added. When a samll amount of polyester-polyether multiblock copolymers was blend with polypropylene from melt
the rheological properties
dyeability and hydroscopic properties of the blend can be improved.
