Abstract: Provided is an EVOH extractant capable of efficiently extracting EVOH from an EVOH layer-containing multilayer resin molded body. Provided is a method for efficiently extracting and recovering EVOH from an EVOH layer-containing multilayer resin molded body. An EVOH extractant including a polar solvent having an SP value of 9 to 13 and a quaternary ammonium salt. An EVOH extraction method for extracting EVOH, including applying the EVOH extractant described above to an EVOH layer-containing multilayer resin molded body. An EVOH recovery method including a step of mixing a solution containing EVOH that has been extracted by the EVOH extraction method described above with water and/or a lower alcohol to deposit EVOH, followed by filtration or centrifugation.

Abstract: A surface conditioner for a coating agent is provided. The surface conditioner for the coating agent comprises: a copolymer composed of 1 to 40 parts by weight of an acrylate monomer (A) having a siloxy group, 2 to 80 parts by weight of an N-vinyllactam monomer (B), and 10 to 97 parts by weight of an alkyl(meth)acrylate monomer (C) of which an alkyl group has 1 to 12 carbon atoms; and weight average molecular weight of the copolymer is 1000 to 120000. It is another object of the present invention to provide a coating agent to which said surface conditioner is blended.

Abstract: Disclosed is a wax that is added to a thermoplastic resin that undergoes a molding process at high temperatures. The wax does not thermally decompose when that thermoplastic resin composition undergoes the molding process. The wax also prevents mold fouling and provides superior lubricating properties and mold release properties. Also disclosed are a method for producing the wax with superior productivity, a lubricant and mold release agent for thermoplastic resin molding processes. The wax contains a dehydration condensed amide wax component. 99.98-5% by weight of which is an acid, which is formed from 2 mol of a C12-22 saturated aliphatic monocarboxylic acid by molar ratio and “a” mole of a C2-12 polybasic acid by molar ratio (0?“a”?5), and “b” mole of a C2-14 diamine by molar ratio (1?“b”?6), and 0.02-5% by weight of an oxidation inhibitor that has compatibility with this amide wax component.
