Utility
Modified vinyl alcohol polymer, method for producing same, dispersion stabilizer for suspension polymerization, and method for producing vinyl polymer
16 Aug 22
The present invention provides a modified vinyl alcohol polymer having a side chain with an ethylenic double bond, and having reduced a water-insoluble content and superior storage stability in the form of an aqueous solution, methods of making thereof, a modified vinyl alcohol polymer (A) having a degree of saponification of 68 mol % or more and less than 99.9 mol %, and a viscosity-average degree of polymerization of 200 or more and less than 3,000, and comprising a side chain with 0.01 mol % or more and less than 0.50 mol % of a double bond derived from an esterification agent, the esterification agent being one or more selected from the group consisting of (i) itaconic acid and/or derivatives thereof, and (ii) methacrylic acid and/or derivatives thereof, and the modified vinyl alcohol polymer (A) having a peak width W0.05h of at least 2.85 minutes and less than 3.70 minutes at a height of 5% from the baseline in a peak measured by HPLC.

Utility
Active Energy Ray Crosslinkable Thermoplastic Polymer and Composition Containing the Same
11 Aug 22
The present invention provides a polymer which has a polymerizable functional group but still can be thermoformed without being crosslinked and which undergoes crosslinking upon irradiation with an active energy ray after being formed, and a composition including the polymer.

Utility
Carbonaceous Material, Method for Producing Same, Filter for Water Purification and Water Purifier
4 Aug 22
One aspect of the present invention relates to a carbonaceous material which has a benzene adsorption of 25 to 40% and a vitamin B12 adsorption of 13.0 to 50.0 mg/g, while having a pore volume of mesopores of 0.070 to 0.150 cm3/g as calculated from a nitrogen adsorption isotherm by means of a BJH method.
