To use a fluorinated copolymer of a fluorinated monomer having a carboxylic acid type functional group with a fluorinated olefin, wherein the proportion of components having a common logarithm (log M) of a molecular weight M being from 2.0 to 3.5 is at most 10 mass % per 100 mass % of components having a common logarithm (log M) of a molecular weight M being at least 2.0, contained in a CClF | 03-13-2014 |
20140121331 | TREATMENT METHOD FOR FLUORORESIN PELLETS - Provided is a treatment method for fluororesin pellets to remove hydrofluoric acid released from fluororesin pellets obtained by melt-molding a melt-moldable fluororesin. The treatment method comprises bringing a hydrofluoric acid-removing medium selected from warm water of from 30 to 200° C., steam of from 100 to 200° C. and warm wind of from 40 to 200° C. into contact with fluororesin pellets obtained by melt-molding a melt-moldable fluororesin, and thereby treating the fluororesin pellets so that the amount of hydrofluoric acid released per kg of the resulting fluororesin pellets would be at most 5 μg as determined after the storage of the resulting fluororesin pellets at 35° C. for 15 days. | 05-01-2014 |
20140187816 | METHOD FOR RECOVERING ANIONIC FLUORINATED EMULSIFIER - To provide a method for recovering an anionic fluorinated emulsifier, whereby an anionic fluorinated emulsifier adsorbed on a basic ion exchange resin can be simply and efficiently recovered. A mixed liquid of an aqueous inorganic acid solution, a fluorinated medium and a non-fluorinated medium, is contacted to a basic ion exchange resin having an anionic fluorinated emulsifier adsorbed thereon, to recover a liquid phase containing the fluorinated medium, or an aqueous inorganic acid solution is contacted to a basic ion exchange resin having an anionic fluorinated emulsifier adsorbed thereon, then a mixed liquid of a fluorinated medium and a non-fluorinated medium is contacted thereto, and thereafter the basic ion exchange resin and a liquid phase are separated to recover the liquid phase, whereupon from each liquid phase, an acid of the anionic fluorinated emulsifier is recovered. | 07-03-2014 |
20150038633 | RESIN COMPOSITION AND USE THEREOF - Disclosed is a resin composition comprising a melt-moldable side chain 1,2-diol-containing PVA-based resin (A), and fluororesin containing a polar functional group capable of reacting with or forming hydrogen bond(s) with hydroxyl group (B). The component (A) and the component (B) have excellent affinity, and therefore if either the component (A) or component (B) becomes matrix, the other can be finely dispersed into the matrix, thus providing a resin composition having excellent gas-barrier property, solvent resistance, and bending fatigue resistance. The present invention also provides emulsified dispersion and binder in which the resin composition is used. | 02-05-2015 |
