MODIFIED POLYPROPYLENE RESIN, FOAM MADE FROM THE RESIN AND PROCESSES FOR THE PRODUCTION OF BOTH

Document Type and Number:

WIPO Patent Application WO/1997/025356

Kind Code:

A1

Abstract:

A modified polypropylene resin is produced by melt-kneading a polypropylene resin, isoprene and a radical polymerization initiator. This resin exhibits such a high viscosity and a high tensile strength in melting that it causes little drawdown. Further, a foam produced by expanding the resin has a low density, a high closed-cell content, a beautiful appearance and an excellent heat resistance.
