Title:
水性ポリアミド−尿素分散物
Document Type and Number:
Japanese Patent JP6507103
Kind Code:
B2
Abstract:
The invention relates to a liquid telechelic prepolymer comprising the reaction product of a telechelic polyamide and a polyisocyanate having two or more isocyanate groups, the telechelic polyamide is characterized as having repeating units connected by linkages between the repeating units and having two or more Zerewitinoff groups that chemically react with isocyanate groups to form a chemical bond between a portion of said Zerewitinoff groups and the isocyanate group, further wherein the telechelic polyamide comprises repeat units connected with chemical linkages characterized as being amide linkages and at least 80 % of the amide linkages are characterized as being tertiary amide linkages, wherein said telechelic prepolymer is the reaction product of a hydroxyl terminated polyamide with a polyisocyanate and said telechelic polyamide is comprised of one or more repeat units from a lactone of 2 or 4 to 10 carbon atoms and/or a hydroxyl carboxylic acid of 3 to 30 carbon atoms. The liquid telechelic prepolymer can be formed into a dispersion in an aqueous media and can be chain extended and formed into a self-supporting film, a coating, or an adhesive.
