摘要：NOVELTY - The invention discloses a method for forming and strengthening the original-position enhancement function of polypropylene blend system. It uses general polymer of polypropylene (PP) as continuous phase, and the polyethylene glycol terephthalate (PET) of project plastic as disperse phase to prepare polymer blend matter; via controlling the structure of blend system to direct disperse phase and make it into fibers; at the same time thermally treating the blend system to improve the crystallized degree of PET, to improve its dynamic property and the effect of original-position enhancement function. With said invention, the dynamic property of polypropylene material can be improved, while the bend strengthen of PP is improved from 37MPa to 55MPa, therefore, it can enlarge the application of polypropylene.
