Abstract
The invention provides a novel binder resin composition. A binder resin composition characterized by comprising carboxyl group-containing chlorinated syndiotactic polyolefin resin with chlorine content of 0.1 to 40 wt. %, grafting level of α,β-unsaturated carboxylic acid and/or its acid anhydride of 10 wt. % and weight average molecular weight of 30000 to 220000 and organic solvent. The carboxyl group-containing chlorinated syndiotactic polyolefin obtainable from polyolefin resin produced using metallocene compound exhibits good state of solution even if the chlorine content may be low, and is excellent in the adherence to polyolefinic prime material and the solvent resistance.
Claims19
A binder resin composition, comprising:
- a carboxyl group-containing chlorinated syndiotactic polyolefin resin with a chlorine content of 10 to 40 wt. %, a grafting level of α,β-unsaturated carboxylic acid and/or its acid anhydride of 1 to 10 wt. % and a weight average molecular weight of 30000 to 220000;
- and
- an organic solvent.
A method of producing a binder resin composition, comprising:
- graft copolymerizing α,β-unsaturated carboxylic acid and/or its acid anhydride onto a syndiotactic polyolefin produced using a metallocene compound as a polymerization catalyst in an amount of 1 to 10 wt. %;
- then chlorinating to a chlorine content of 10 to 40 wt. %, thereby obtaining a carboxyl group-containing chlorinated syndiotactic polyolefin resin;
- and
- dissolving the carboxyl group-containing chlorinated syndiotactic polyolefin resin having a weight average molecular weight of 30000 to 220000 in an organic solvent.
