摘要:
Disclosed is a porous metal oxide obtained by subjecting metal alkoxide and/or a partially hydrolyzed condensate of the metal alkoxide to a sol-gel reaction in the presence of terminally branched copolymer particles represented by the following general formula (1) and having a number average molecular weight of not more than 2.5×104 to obtain an organic-inorganic composite and removing the terminally branched copolymer particles from the composite.

摘要:
Polymers having polyolefin segments as the side chain, with a structural unit represented by the following Formula (1): wherein A is an olefin polymer having a weight average molecular weight of 400 to 500,000; R is H, an alkyl group, or an aralkyl group; W and Z are each O, HN, or S; and x and y are each 0 or 1, with the proviso that at least one of them is 1. The polymer can be applied as an antistatic agent, a cosmetic additive, a releasing agent for toner, a pigment dispersant, a lubricant for vinyl chloride resins, a coating material, an emulsion composition and the like.
摘要:
An antifouling material and an antifouling film, which are excellent in hydrophilicity and have such a characteristic that the surface is self-cleaned with rain water or the like, or can be easily cleaned up even when a contaminant adheres to the surface thereof, can be obtained by copolymerizing a composition containing an acrylamide derivative having at least one hydroxyl group in the molecule and a compound having at least two (meth)acryloyloxy groups in the molecule.
摘要:
Organic polymers having water contact angles of 20° or smaller, preferably 7° or smaller and equipped with both high wettability and high transparency. The organic polymers may contain as partial structures polar structures of about 3 debyes or higher in dipole moment and are available especially from polymerization of polymerizable compounds having alkylene(thio)urea structures.
