Abstract
PURPOSE: A composition of polyolefin resin containing a filler and a liquid rubber at a specific ratio is melt-formed and drawn to produce a porous film or sheet suitably used as water-proofing commodities or filtration material, because of its high surface strength and high flexibility.
CONSTITUTION: (A) A powder of polyolefin resin such as high-density polyethylene (100pts.wt.) is placed in a mixer such as Henschel mixer and (B) a liquid rubber such as liquid polybutadiene is added, preferably by 10W30pts. and they are stirred. Further, (C) a filler such as calcium carbonate is added, preferably by 60W150pts. and stirred to give the objective composition. The composition is kneaded and granulated, subjected to inflation into a film or sheet. Then, the film or sheet is monoaxially drawn at a 1.5W3 draw ratio or biaxially at a 1.2W2 draw ratio to produce a porous film or sheet.
