A parison is hung down between a pair of molding metallic molds in the opened state, expanding members are contacted with the specified portions of the parison, and after setting the temperature difference between the specified portions and other portions in accordance with a pre-set thickness ratio between both portions after forming thereof, the expanding members are moved while cooling the specified portions of expanding members so as to extend and thin the portions other than the specified portions of the parison, and the metallic molds are closed together so as to blow compressed air into the parison to effect blow-molding.

Blow-molding method for resinous molding product and apparatus therefor

A composition which comprises polyphenylene ether, polyamide, rubber-like material, compatibilizing agent having double bond or triple bond, and a polarity such as a carboxyl group, amide group and the like, and a melt tension modifier comprising a compound having oxirane oxygen. Said composition makes blow molding of large size molded products possible by the effect of decreasing the drawdown of parison during blow molding.
