Abstract:
A binder resin for polyolefinic resins comprising carboxyl group-containing chlorinated polyolefin (II), which is a carboxyl group-containing chlorinated polyolefin obtainable by graft copolymerizing at least one kind of unsaturated carboxylic monomer selected from carboxylic acid and/or carboxylic anhydride onto a polyolefin (I) in amounts of 1 to 10 wt. % and then chlorinating to chlorine content of 10 to 30 wt. %, which contains not more than 2% wt. of a component with molecular weight of 2,000 or lower, being the low-molecular weight region of said carboxyl group-containing chlorinated polyolefin, and which carboxyl group-containing chlorinated polyolefin (II) has a ratio (Mw/Mn) of weight average molecular weight (Mw) to number average molecular weight (Mn) of not more than 4.
