The present disclosure 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, wherein compound E is a carboxylic acid or anhydride with functionality of at least 2, to obtain carboxyl-functional, unsaturated polyester F, and 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.

Disclosed are a novel monofunctional polyethylene glycol (PEG) and derivatives thereof. More particularly, one terminal of each of the monofunctional polyethylene glycol and derivatives thereof is modified with a siloxy group. The novel monofunctional polyethylene glycol (PEG) offers an alternative to methoxy polyethylene glycol.

The present invention relates to micellar nanocomplexes and a method of forming the same. The micellar nanocomplex comprises a micelle and an agent encapsulated within said micelle, where the micelle comprises a polymer-flavonoid conjugate, wherein said polymer is bonded to the B ring of said flavonoid. The micellar nanocomplex may have useful applications as a drug-delivery system.

The present invention relates to thermoplastic polyamides (PA) comprising recurring units derived from a PFPE dicarboxylic acid (PFPA-DA) or a PFPE diamine (PFPE-NN) in a defined weight amount with respect to other units derived from the other monomers used in the course of polymerization. Polyamides (PA) are endowed with improved surface properties, chemical resistance and reduced brittleness and do not require the addiction of impact modifiers.

The present invention is related to a product for the resolution of racemic mixtures in which various separation processes of a salt composed of a PEGylated resolving agent and an enantiomer in a racemic mixture is utilized. Separation can be caused by temperature-dependent phase transformation of the said salt pair in aqueous or organic media as well as other methods used is separation of PEG such as salting out (e.g. addition of ammonium sulfate). The first cycle of racemic resolution by this method was shown to afford 85% optically pure amino acid from a 50:50 mixture of racemic L,D-amino acids esters. An additional cycle improved optical purity up to 95%.
