POLYLACTIC ACID AQUEOUS EMULSION, PRODUCTION METHOD THEREFOR AND COATING MATERIAL CONTAINING THE SAME EMULSION

摘要

PPROBLEM TO BE SOLVED: To prepare a polylactic acid aqueous emulsion having excellent handling workability, safety, storage stability, or the like, and to provide a production method therefor. PSOLUTION: The polylactic acid aqueous emulsion comprises a compound expressed by the formula (1): Fa-COO-[(CHRSP1/SP)SBl/SB(CHRSP2/SP)SBm/SB-O]SBn/SB[(CHRSP3/SP)SBl'/SB(CHRSP4/SP)SBm'/SB-O]SBn'/SB-RSP5/SP[in the formula, Fa is a 4-12C alkyl group; RSP1/SP, RSP2/SP, RSP3/SPand RSP4/SPare each hydrogen atom or methyl group; RSP5/SPis a 1-8C alkyl group; (l), (l'), (m) and (m') are each an integer of 0-6 (1l+m6 and 1l'+m'6); and (n) and (n') are an integer of 0-5 (1n+n'5)].
