Abstract:
The invention provides a radiation-curable alkoxy silanized hyperbranched polyester acrylate, characterized in that the radiation-curable alkoxy silanized hyperbranched polyester acrylate is produced by using a hyperbranched molecule with at least 16 functionalities as a core; acrylating or methacrylating a portion of the terminal groups of the hyperbranched molecule; and terminating a portion of the end groups of the hyperbranched molecule with an isocyanated silane coupling agent. The acrylate of the invention can be formed into a coating on polar substrates, such as glass or metal, or used as an adhesive.
Abstract:
New anti-reflective or fill compositions having improved flow properties are provided. The compositions comprise a dendritic polymer dispersed or dissolved in a solvent system, and preferably a light attenuating compound, a crosslinking agent, and a catalyst. The inventive compositions can be used to protect contact or via holes from degradation during subsequent etching in the dual damascene process. The inventive compositions can also be applied to substrates (e.g., silicon wafers) to form anti-reflective coating layers having high etch rates which minimize or prevent reflection during subsequent photoresist exposure and developing.
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.
