    摘要: To prepare a polyester polyol in which a lactone is ring-opening addition polymerized with the compound represented by formula (I). (wherein each of A1 and A2 represents an alkylene group having not less than 2 carbon atoms, A3 represents an alkylene group, X represents a cationic component, and each of n and m represents an integer of not less than 1.)The polyester polyol has a high hydrophilic group and high solubility in a solvent (particularly, a low-boiling organic solvent used in the production of a polyurethane) and can design an aqueous polyurethane desirably and produce the aqueous polyurethane.

    摘要: The present invention provides a hot melt adhesive composition comprising an epoxy-modified block copolymer obtained by epoxidizing a carbon-carbon double bond of a conjugate diene component in a block copolymer having a polymer block (A) comprising mainly a vinyl aromatic compound and a polymer block (B) comprising mainly a conjugate diene compound in one molecule, a paraffin wax having a melting point of 40 to 100.degree. C., a tackifier and an antioxidant. The hot melt adhesive composition of the present invention is well compatible with a paraffin wax and a tackifier because it has an epoxy group which is a polar group in a molecule. Further, the hot melt adhesive composition has excellent heat resistance and cold resistance because of a combination of the epoxy-modified bloc copolymer as a base polymer with paraffin wax, and while the melt viscosity is low, the heat resistance is high.
