AQUEOUS DISPERSION COMPRISING A GRAFT-MODIFIED PROPYLENE/ -OLEFIN COPOLYMER

A graft-modified propylene·±-olefin copolymer (A) is obtained by graft-reacting a polar monomer onto a propylene·±-olefin copolymer (a) including 50 to 90 mol% of propylene-derived structural units (C3) and 10 to 50 mol% of C 4-8 ±-olefin-derived structural units (C±) (wherein the total of the struc...

Zusammenfassung:	A graft-modified propylene·±-olefin copolymer (A) is obtained by graft-reacting a polar monomer onto a propylene·±-olefin copolymer (a) including 50 to 90 mol% of propylene-derived structural units (C3) and 10 to 50 mol% of C 4-8 ±-olefin-derived structural units (C±) (wherein the total of the structural units C3 and C± is 100 mol%), and satisfies the following requirements (i) to (iv) at the same time: (i) the amount of the polar monomer grafted is 0.4 to 1.5 wt%, (ii) the content of the polar monomer is not more than 1000 ppm, (iii) the content of a gel insoluble in xylene at 140°C is not more than 2.5 wt%, and (iv) the content of a volatile hydrocarbon compound is not more than 10 ppm.
