POLYLACTIC ACID-CONTAINING AQUEOUS DISPERSION

摘要

To provide a polylactic acid-containing aqueous dispersion which is capable of forming a transparent film at room temperature. A polylactic acid-containing aqueous dispersion which contains: (1) a polylactic acid; (2) one or more plasticizers selected from the group consisting of dimethyl adipate, diethyl adipate, dipropyl adipate, diisopropyl adipate, dibutyl adipate, diallyl adipate, bis(2-butoxyethyl) adipate, bis(2-methoxyethyl) adipate, dimethyl succinate, dimethyl glutarate, diethyl sebacate, diisopropyl sebacate and mixtures of these compounds; (3) one or more dispersion stabilizers selected from the group consisting of cationic polymer compounds, anionic polymer compounds, polyvinyl alcohols and nonionic surfactants; and (4) water.
