Polymers containing halogen functionality are prepared by the addition or condensation polymerization of at least one halogenated reactant containing at least two active hydrogen-containing functional groups per molecule and at least one halogenated heteroalkyl or halogenated heteroalkenyl group per molecule and at least one co-reactant containing at least two functional groups reactive with the active hydrogen groups of the at least one halogenated reactant.

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.

The invention relates to an aqueous dispersion of a carboxyl-functional, unsaturated polyester containing a perfluoropolyether block prepared by the following steps: a) subjecting a carboxyl-terminated perfluoropolyether C to a reaction with an ethylenically unsaturated epoxy-functional compound D in the presence of compound E, which is a carboxylic acid or anhydride with functionality of at least 2, to obtain carboxyl-functional, unsaturated polyester F, b) neutralizing carboxyl-functional, unsaturated polyester F with a neutralizer G and dispersing it in water. The dispersion can be used to prepare a waterborne, UV-curable coating composition and used for easy-clean coatings for various substrates.

Methods of making multi-block copolymer that reduce the tendency for large phase domains to form provide copolymer compositions that are useful for various applications, including the manufacture of medical devices.
