BINDER RESIN COMPOSITIONS, PRODUCTION PROCESS, AND USE THEREOF

摘要

A binder resin composition containing a chlorinated propylene random copolymer which is obtained by copolymerizing propylene in the presence of a metallocene catalyst to obtain a propylene random copolymer having a melting point (Tm) as measured with a differential scanning calorimeter (DSC) of 115 to 165°C and chlorinating the random copolymer to a chlorine content of 10 to 40 wt.% and which has a weight-average molecular weight of 3,000 to 250,000; and a binder resin composition containing a carboxylated chlorinated propylene random copolymer which is obtained by copolymerizing propylene in the presence of a metallocene catalyst to obtain a propylene random copolymer having a Tm as measured with a DSC of 115 to 165°C, grafting 0.1 to 20 wt.% alpha,ß-unsaturated carboxylic acid or anhydride thereof onto the random copolymer, and then chlorinating the graft copolymer to a chlorine content of 10 to 40 wt.% and which has a weight-molecular weight of 30,000 to 220,000.
