    摘要: Linear, comb, and star shaped non-ionic polyesters and copolyesters, polyesteramides, polyamides, and copolyamides may be synthesized from the condensation polymerization of polyacids containing alpha-hydroxy polyacids and diols and/or polyols, and amino-diols and/or amines using boric acid, boric anhydride, and boronic acids as catalysts. Depending on the polyol, polyamine, and amino alcohol component, the resulting compound may be hydrophilic or hydrophobic, but not water soluble or dispersible, enabling use in packaging films, fibers, and other molded articles. The compounds may be completely water soluble, water dispersible, and/or amphipathic, thus being useful in cosmetics, agricultural compositions, biomedical and pharmaceutical applications.
