NOVEL METHODS FOR SOL-GEL POLYMERIZATION IN ABSENCE OF SOLVENT AND CREATION OF TUNABLE CARBON STRUCTURE FROM SAME
The present application is directed to methods for solvent-free preparation of polymers and their subsequent processing into activated carbon materials. These methods unexpectedly demonstrate ability to tune pore structure in the polymer gel and carbon produced there from, while also providing distinct advantages over the current art.
Photosensitive adhesive composition
A novel photosensitive adhesive composition including the following components (A), (B), (C), and (D): Component (A): a polymer having a structural unit of the following formula (1) and a structure of the following formula (2) at a terminal, Component (B): a polymer having the structural unit of formula (1), and a carboxy group or hydroxy group at a terminal, Component (C): a radical photopolymerization initiator, and Component (D): a solvent, wherein the content by mass of the component (B) is larger than that of the component (A), ##STR00001##
(wherein X is a C.sub.1-6 alkyl group, a vinyl group, an allyl group, or a glycidyl group, m and n are each independently 0 or 1, Q is a divalent C.sub.1-16 hydrocarbon group, Z is a divalent C.sub.1-4 linking group, the divalent linking group being bonded to an O group in formula (1), and R.sup.1 is a hydrogen atom or a methyl group.)
Controlled crosslinking of latex polymers with polyfunctional amines
The latex polymer compositions of the present invention exhibit latent crosslinking properties. Latent crosslinking in the polymers takes advantage of the fast interaction between the anionic latex charge and the cationic charge associated with polyfunctional amine crosslinkers. Once the latex is coated onto a substrate, the volatile base evaporates and the groups react to form a crosslinked coating with improved wash-off properties.
