Abstract:
1. An aqueous dispersion comprising a carboxyl group-containing chlorinated propylenic isotactic random copolymer produced with a metallocene catalyst and with chlorine content of 5 to 40% by weight, based on amount of carboxyl group-containing chlorinated propylenic isotactic random copolymer, grafting level of α,β-unsaturated carboxylic acid or its anhydride of 0.1 to 20% by weight, based on raw material propylenic isotactic random copolymer, a weight average molecular weight of 10,000 to 300,000, and a melting point of from 115 to 135° C. as measured by differential scanning calorimetry; and stabilizer.
