Blended polyolefin dispersions

摘要

Blended polyolefin dispersions, including: (A) a liquid; (B) an olefin-based polymer dispersed in the liquid, the dispersed olefin-based polymer having an average particle size ranging from 0.1 to 5 microns; and (C) an alpha-beta unsaturated carboxylic acid-based polymer dispersed in the liquid, the dispersed alpha-beta unsaturated carboxylic acid-based polymer having an average particle size ranging from 0.02 microns to 1 micron. Coatings, froths, foams, toners, and other various uses for the blended dispersions are also disclosed.

1. A blended polyolefin dispersion comprising:
a blend dispersion formed from (A) a first dispersion comprising (i) an ethylene/α-olefin multi-block copolymer having hard segments and soft segments and (ii) a surfactant, the dispersed ethylene/α-olefin multi-block copolymer having an average particle size ranging from 0.1 to 5 microns; and (B) a second dispersion having a pKa greater than or equal to 10 and comprising an alpha-beta unsaturated carboxylic acid-based polymer, the dispersed alpha-beta unsaturated carboxylic acid-based polymer having an average particle size ranging from 0.02 microns to 1 micron, wherein the average particle size of (A) is larger than the average particle size of (B).
