Abstract: A hydrogel tissue adhesive having decreased gelation time and decreased degradation time is described. The hydrogel tissue adhesive is formed by reacting an oxidized polysaccharide containing aldehyde groups with a water-dispersible, multi-arm amine in the presence of a thiol additive. The thiol additive accelerates the process to form the hydrogel and accelerates the degradation of the hydrogel formed. The hydrogel may be useful as a tissue adhesive or sealant for medical applications, such as a hemostat sealant or to prevent undesired tissue-to-tissue adhesions resulting from trauma or surgery.
Abstract: Acid generator compounds are provided that comprise an oxo-1,3-dioxolane moiety and/or an oxo-1,3-dioxane moiety. The acid generators are particularly useful as a photoresist composition component.

Abstract: A method of forming a pattern comprises diffusing an acid, generated by irradiating a portion of a photosensitive layer, into an underlayer comprising an acid sensitive copolymer comprising an acid decomposable group and an attachment group, to form an interpolymer crosslink and/or covalently bonded to the surface of the substrate. Diffusing comprises heating the underlayer and photosensitive layer. The acid sensitive group reacts with the diffused acid to form a polar region at the surface, in the shape of the pattern. The photosensitive layer is removed to forming a self-assembling layer comprising a block copolymer having a block with an affinity for the polar region, and a block having less affinity than the first. The first block forms a domain aligned to the polar region, and the second block forms a domain aligned to the first. Removing either the first or second domain exposes a portion of the underlayer.
