摘要： The present invention provides a novel angiogenesis device. The angiogenesis device comprises an angiogenic component and a polymer, and is used to induce angiogenesis at a site for implantation of a cell- or tissue-containing device. The polymer may comprise, for example, at least one or more polyvinyl alcohol resins (A) selected from a modified polyvinyl alcohol resin having an active carbonyl group (A1), a polyvinyl alcohol resin having a triad syndiotacticity of 32 to 40% (A2), and a polyvinyl alcohol resin having a degree of saponification of 97 mol % or more (A3).

摘要： A novel binder is provided. The binder comprises a polyvinyl alcohol-based polymer which has an average saponification value of 85.0 mol % to 89.0 mol % as measured according to JIS K6726 and meets requirement (A): a fluid prepared by adding 130.0 mL of 1-propanol to 100.0 g of a 5.0% by mass aqueous solution of the polyvinyl alcohol-based polymer has a transparency of 80.0% or less at 20° C.; and/or requirement (B): a supernatant from a fluid prepared by adding 230.0 mL of 1-propanol to 100.0 g of a 5.0% by mass aqueous solution of the polyvinyl alcohol-based polymer has a concentration of 0.65% by mass or more at 20° C.

摘要： Provided is a dispersion stabilizer which exhibits an excellent polymerization stability when used in suspension polymerization for a vinyl chloride-based resin, and gives a vinyl chloride-based resin having few coarse particles, few fish eyes after resin molding, an excellent plasticizer absorption, and an excellent hue. Also provided is a high-quality vinyl chloride-based resin produced using the dispersion stabilizer. The present invention is a dispersion stabilizer for suspension polymerization containing a polyvinyl alcohol-based polymer (B) which has a double bond in a side chain and which is obtainable by acetalization of a polyvinyl alcohol-based polymer (A) with a monoaldehyde having an olefinic unsaturated double bond.
