ABSTRACT:
The invention relates to polymer resins which are dispersible or soluble in water, wherein the resin is an amorphous, chlorinated, chemically modified copolymer or terpolymer prepared from polyethylene, polybutene and/or polypropylene and having an amorphous polypropylene content of at least 50% by weight, an average molecular weight Mw of 10,000 to 100,000 g/mol, a non-uniformity of 1.0 to 6.5, a chlorine content of 2.5 to 50% by weight, an anionic or cationic salt group content of 5 to 250 milliequivalents per 100 g of polymer resin and a content of polyoxyalkylene units of 0 to 40% by weight, the proportion of oxyethylene units being at least 30% by weight of the oxyalkylene units.
