Methods and Compositions for Providing Preferential Adhesion and Release of Adjacent Surfaces
The present invention provides a method and composition for providing preferential adhesion and release of adjacent surfaces, that features solidifying a composition to form a solidified layer having first and second opposed sides, with the first side facing a first surface and being adhered thereto with a first adhesive forces and the second side facing the second surface and being adhered thereto with a second adhesive force, with the first and second adhesive forces establishing a predetermined preferential adhesion ratio. Generally, the first surface is covalently bonded to the first side and adhesion between the second side and the second surface occurs through Van der Waal forces. It has been found that the use of a fluorine group for enhancing the release properties (as a priori fluorinated release layer or a fluorinated release agent) is no longer needed for such method and composition. In one embodiment, the composition can be formed from an isobornyl acrylate component; an aliphatic urethane acrylate component; a 1,6-hexanediol diacrylate component; and a 2-hydroxy-2-methyl-1-phenyl-propan-1-one component. The first surface can be formed by polymerizing a compound formed from a multi-functional component that contains functional groups facilitating the formation of covalent bonds with the above mentioned polymerizable composition during an imprinting process, a cross-linking agent component, a catalyst component, and a solvent component. The second surface is usually a patterned or smoothed portion of a quartz mold.

Process for producing 1,6-hexanediol and coproducing epsilon-caprolactone
ActiveCN102351648AEfficient use ofEasy to separateOrganic compound preparationHydroxy compound preparationCatalytic distillationAdipic acid
The invention provides a process for preparing 1,6-hexanediol and coproducing epsilon-caprolactone through esterification and hydrogenation of adipic acid. The process comprises the following steps of: performing countercurrent contact of pure adipic acid and methanol steam on a catalyst active ingredient-loaded filler in a reaction catalytic distillation tower, and performing esterification reaction; and purifying dimethyl adipate, and performing hydrogenation purification to obtain the 1,6-hexanediol and coproduce epsilon-caprolactone, wherein polymer generated after product separation is subjected to ester exchange reaction to be recycled. The catalyst has high activity and selectivity, the products are high in yield, energy consumption is low, the equipment investment is small, the catalyst is environment-friendly, and the preparation process is simple, economic and practical.

Reactive polyurethane hotmelts with large PSA range
Reactive polyurethane hotmelts comprising crystallizing polyesterpolyols based on fumaric acid and 1,6-hexanediol. These hotmelts exhibit good pressure-sensitive adhesive (PSA) properties over a very broad temperature range. The reactive polyurethane hotmelts are prepared by mixing a polyol mixture containing at least on crystallizing polyesterpolyol with an excess of polyisocyanates.
