Abstract:
1. A process for producing a polypropylene type aqueous dispersion, said process comprises dispersing following component (a) in component (c) with component (b); (a) a polypropylene type polymer and/or a modified polypropylene type polymer, prepared by a single site catalyst 100 parts by weight, (b) a surfactant 1 to 100 parts by weight, and (c) water 100 to 1,000 parts by weight, wherein the component (a) has a main chain having the following features (1) and (2) and dispersion particles in the dispersion have an average particle size of at most 0.5 μm, Feature (1) when observing a peak derived from a carbon atom of a methyl group in a propylene unit chain part comprising a head-to-tail bond by Feature (2) a content ratio (mol ratio) of propylene unit (A): other olefin unit (B) is from 100:0 to 90:10.
