Mixture for melt process moldings having long fiber reinforced polypropylene and polypropylene resin and high mechanical strength molding formed therefrom

A melt process molding obtained by melting and molding a melt process molding mixture consisting essentially of about 5 to about 70 wt % of a glass fiber reinforced polypropylene resin in the form of pellets as a master batch and about 30 to about 95 wt % of another polypropylene resin to dilute said master batch, said melt process molding containing glass fibers having an average length of about 0.8 to about 10 mm, said glass fiber reinforced polypropylene resin being prepared bundling continuous reinforcement glass fibers surface-finished with a finishing agent containing a coupling agent and impregnating the resulting bundle with a modified polypropylene resin having a functional group capable of chemically bonding with the coupling agent and having a melt flow rate of about 70 to about 300 g/10 rain (ASTM D-1238, load:

• 2.16 kg, temperature:
• 230.degree. C.) while the bundle is being drawn, said pellets being formed by cutting said glass fiber reinforced polypropylene resin, said pellets having a length of about 2 to about 50 mm in the direction along the fibers, the glass fibers in said pellets extending uniformly in parallel with each other through a distance substantially equal to the length of said pellets, said pellets having a glass fiber content of about 60 to about 90 wt %.
