Abstract
The present invention relates to a halogen-based resin composition containing a plasticizer, a polymer dispersant, a basic inorganic filler and a halogen-based resin, in which the polymer dispersant contains a carboxy group-containing constitutional unit and a hydrophobic group-containing constitutional unit; a degree of neutralization of the polymer dispersant is not more than 30 mol %; and a weight-average molecular weight (Mw) of the polymer dispersant is not less than 4,000 and not more than 200,000.
Claims20
A halogen-based resin composition comprising a plasticizer, a polymer dispersant, a basic inorganic filler and a halogen-based resin, in which:
- the polymer dispersant comprises a carboxy group-containing constitutional unit and a hydrophobic group-containing constitutional unit;
- a degree of neutralization of the polymer dispersant is not more than 30 mol %;
- a weight-average molecular weight (Mw) of the polymer dispersant is not less than 4,000 and not more than 200,000;
- and
- a mass ratio of the polymer dispersant to the basic inorganic filler is not less than 0.0005 and not more than 0.1.
(canceled)
A polymer dispersant comprising a carboxy group-containing constitutional unit and a hydrophobic group-containing constitutional unit, wherein
- a degree of neutralization of the polymer dispersant is not more than 30 mol %;
- and
- a weight-average molecular weight (Mw) of the polymer dispersant is not less than 4,000 and not more than 200,000.
