Abstract
A molded fibrous basic magnesium sulfate filler-containing olefin polymer composition product is produced by a process comprising the steps of preparing a fibrous basic magnesium sulfate filler-containing master batch composition which comprises an olefin polymer, a fibrous basic magnesium sulfate filler, an elastomer, a fatty acid metal salt and a hydrocarbon or silicone oil or a hydrocarbon or silicone wax; mixing the master batch composition and a propylene polymer-containing diluent resin; kneading the resulting mixture in a molten state; and molding the molten mixture to give the molded product.

A process for producing a molded fibrous basic magnesium sulfate filler-containing olefin polymer composition product which comprises the steps of:
- preparing a fibrous basic magnesium sulfate filler-containing master batch composition which comprises the following components:
- (A) an olefin polymer,
- (B) a fibrous basic magnesium sulfate filler,
- (C) an elastomer,
- (D) a metal salt of a fatty acid, and
- (E) a hydrocarbon or silicone oil or a hydrocarbon or silicone wax;
- mixing 100 weight parts of the fibrous basic magnesium sulfate-containing master batch composition and 100 to 2,000 weight parts of a diluent resin containing a propylene polymer, to give a mixture;
- kneading the resulting mixture in a molten state, to give a molten mixture;
- and
- molding the molten mixture to give the molded product.
A fibrous basic magnesium sulfate filler-containing master batch composition which comprises the following components:
- (A) an olefin polymer,
- (B) a fibrous basic magnesium sulfate filler,
- (C) an elastomer,
- (D) a metal salt of a fatty acid, and
- (E) a hydrocarbon or silicone oil or a hydrocarbon or silicone wax;
- wherein the batch composition comprises the component (A) in an amount of 1 to 45 weight parts, the component (B) in an amount of 35 to 80 weight parts, and the component (C) in an amount of 5 to 45 weight parts under the condition that the total amount of the components (A), (B) and (C) is 100 weight parts, and the component (D) in an amount of 0.01 to 15.0 weight parts and the component (E) in an amount of 0.01 to 15.0 weight parts under the condition that the amount of the component (D) is in the range of 0.02 to 20.0 weight parts and the amount of the component (E) is in the range of 0.02 to 20.0 weight parts, per 100 weight parts of the component (B).
