Abstract:
A chlorinated propylene-based polymer of the present invention having a weight average molecular weight (Mw) as measured by gel permeation chromatography (GPC) of 5,000 to 100,000 and a chlorine content of 0.1 to 70% by mass has the following properties: (1) it has a high solubility in a non-aromatic solvent having a low environmental burden even when it has a low degree of chlorination, and (2) it can be inhibited from suffering a decrease in the properties inherent to polypropylenes, such as durability, mechanical properties, appearance and hydrophobicity, by regulating its degree of chlorination at a low value.
