In a recentpaper [1] thepreparation techniques, str-rlctlrral features, crystallization, melting characteristics, and certain properties of the beta-modification of isotactic polypropylene (beta-IPP) were reviewed Possible uses of beta-IPP were demonstrated through example applications. The problems involved with the processing of beta-nucleated polypropylene were analyzed and the conditions of the processing technology of beta-IPP end-products were discussed. In the present paper, the results of the studies on the injection moulding technology of a commercial beta-nucleated polypropylene are addressed.
