Abstract
Official abstract text for this publication.
An emulsion containing a block copolymer (I) and a dispersant (II), wherein the block copolymer (I) contains a block structural unit (A) containing a polylactic acid unit (a) as a main component and a block structural unit (B) containing a polyester unit (b) as a main component.
First claim
Opening claim text (preview).
1 . An emulsion comprising a block copolymer (I) and a dispersant (II), wherein the block copolymer (I) contains a block structural unit (A) containing a polylactic acid unit (a) as a main component and a block structural unit (B) containing a polyester unit (b) as a main component. 2 . The emulsion according to claim 1 , wherein the block copolymer (I) is 50% by mass or more and 99% by mass or less based on a total of 100% by mass of the block copolymer (I) and the dispersant (II). 3 . The emulsion according to claim 1 , wherein the polyester unit (b) contains a unit derived from an aliphatic diol (b1) and an aliphatic dicarboxylic acid (b2), and the aliphatic diol (b1) is a diol having an alkyl group as a branched chain. 4 . The emulsion according to claim 3 , wherein the aliphatic diol (b1) has 10 or less carbon atoms. 5 . The emulsion according to claim 3 , wherein the aliphatic diol (b1) has 5 or more carbon atoms. 6 . The emulsion according to claim 3 , wherein the branched chain of the aliphatic diol (b1) is a methyl group. 7 . The emulsion according to claim 1 , wherein the block structural unit (A) is 5% by mass or more and 95% by mass or less based on a total of 100% by mass of the block structural unit (A) and the block structural unit (B). 8 . The emulsion according to claim 1 , wherein the dispersant (II) is a vinyl alcohol polymer. 9 . The emulsion according to claim 1 , having a particle size of 100 to 1,000 nm. 10 . A method for producing the emulsion according to claim 1 , comprising the step of: dispersing the block copolymer (I) dissolved in an organic solvent in an aqueous medium in presence of the dispersant (II). 11 . The method for producing the emulsion according to claim 10 , further comprising: removing the organic solvent.
