摘要:
Processes comprising: (a) providing a carboxylic acid having at least two carboxy groups, and an amino alcohol having at least one amino group and at least two hydroxy groups; and (b) reacting the carboxylic acid and the amino alcohol in a molar ratio selected from ratio values of; (i) 1.1:1 to 1.95:1, to form a highly branched or hyperbranched polyesteramide; and (ii) 2:1 to 10:1, to form a prepolymer, and reacting the prepolymer with a monomer having at least one functional group to form a highly branched or hyperbranched polyesteramide; polyesteramides thus formed; and objects made from such polyesteramides.
