Abstract:
     The beta-crystalline polypropylene of this invention contains 80-93% beta-crystalline polypropylene. The beta-crystalline nucleator composed with dual-constituent of 1 x 10-2 -1% wt. organic binary acid and 0.2-1% wt. alkali earth metal compound of second group in periodic table, is mixed with polypropylene, via melting and grinding to produce beta-crystalline polypropylene. This beta-crystalline polypropylene is a raw material for making high anti-shock articles, film and fiber etc.
