Abstract:
The present invention relates to a polymer composition comprising: (i) one or more dendritic polymers; and (ii) a reactive diluent that is capable of being chemically coupled to the functional groups of the dendritic polymers, wherein when the dendritic polymer is coupled to the reactive diluent in the presence of a cross-linker, a polymerized solid is formed at high concentrations in a liquid medium. The present invention further relates to methods of preparing the polymer composition and its use in forming coatings.

Abstract:
An oxygen-scavenging composition is provided that includes an oxygen-scavenging polymer and a catalyst. The oxygen-scavenging polymer, which in preferred embodiments is suitable for use in packaging articles, is a dendritic polymer having one or more oxygen-scavenging groups.
Abstract:
The invention herein relates to a surface protective dendritic polymer composition and to the cross-linked surface protective coating formed therefrom.
Abstract:
Provided is a photo-curable coating composition which can be widely used as a coating material for a variety of substrates. The coating composition comprises 80 to 800 parts by weight of methylmethacrylate, 80 to 150 parts by weight of trimethylol propane triacrylate or a dipentaerythritol penta/hexa acrylate mixture, and 10 to 30 parts by weight of a photoinitiator, based on 100 parts by weight of the hyperbranched urethane acrylate prepolymer. The coating composition of the present invention is free from environmental regulations due to no use of an organic solvent and has superior working efficiency due to a low viscosity resulting in spray-coatability and high heat, abrasion, scratch, chemical and yellowing resistance. Therefore, the composition of the present invention can be widely used as a coating material for a variety of substrates.
Abstract:
Powder coating materials which comprise high-functionality, highly branched or hyperbranched polycarbonates based on dialkyl carbonates or diaryl carbonates or phosgene, diphosgene or triphosgene and on aliphatic, aliphatic/aromatic or aromatic diols or polyols.
Abstract:
Novel hyperbranched segmented copolymers include at least one oligomer. Spacing of branch points in a hyperbranched hyperbranched polymer (A 2 B n ) x are manipulated by having either A 2 or B n or both A 2 and B n be in the form of an oligomer (as opposed to a monomer).
Abstract:
The present invention provides a biodegradable, biocompatible polymer that is capable of forming particles (micelles), vesicles, surfaces and membranes, and other structures in which a biologically active agent, e.g. a drug, can be incorporated in such a way that its release to the host can be controlled to a high degree of accuracy, or in where surfaces of the formed polymers can be used to increase the hemeo compatibility of biomaterials. The present invention provides polymer compounds comprising at least one biodegradable polyester having a terminal functional group based on hydrophilic moieties from a phospholipid.
