This disclosure provides an investigation of the kinetic uptake properties of water in amorphous PEF and PET across the entire water activity interval at various temperatures, and also investigates the corresponding equilibrium uptake properties at the same conditions. Uptake data were measured using three independent and complementary methodologies, and excellent agreement was observed among all three methodologies. Accordingly, this disclosure provides for methods of plasticizing poly(ethylene furanoate) film by cold water sorption, and provides a plasticized poly(ethylene furanoate) (PEF) film made according to the disclosed methods. Methods for making thin films of PEF are also provided.

A method for producing particles, the method including: depolymerizing a resin to obtain a depolymerized product; contacting the depolymerized product obtained in the depolymerizing with a first compressive fluid to obtain a melted product; and jetting the melted product obtained in the contacting to granulate the particles.

The present invention provides: a water-soluble film that is superior in cold water solubility and in practical properties such as strength and stiffness and that can resist deterioration in various properties such as chemical resistance over time; and a modified polyvinyl alcohol used for the water-soluble film. The present invention relates to a modified polyvinyl alcohol containing 0.05 to 10 mol % of a monomer unit having two carboxyl groups. In .sup.1H-NMR spectroscopy of the modified polyvinyl alcohol, an integral (X) from 6.8 to 7.2 ppm and an integral (Y) from 5.3 to 5.5 ppm satisfy the following expression:

0.60≦X/(X+Y)<1.0.

A production method comprising: (a) a step of melt-mixing a base resin containing a chlorinated polyethylene; an organic peroxide, an inorganic filler, and a silane coupling agent, in specific ratios, at a temperature equal to or higher than a decomposition temperature of the organic peroxide, to prepare a silane master batch; (b) a step of mixing the silane master batch obtained in the step (a) with a silanol condensation catalyst, and then forming the resultant mixture; and conducting at least one of the melt-mixing in the step (a) and the mixing in the step (b) is performed in the coexistence of a chloroprene rubber or a polyvinyl chloride; a heat-resistant chlorine-containing crosslinked resin formed body produced by the method, a silane master batch, a mixture and formed body thereof, and a heat-resistant product.

Polyester-based films contain certain copolyesters (A) and polyester plasticizers (B). The copolyesters (A) may be selected from those in which the force required to stretch a film of the copolyester (A) by itself, from 2× to 5×, increases by less than 200%. The polyester plasticizers (B) have a weight-average molecular weight of 900 to 12,000 g/mol, and contain (i) a diol component comprising residues of diols having 2 to 8 carbon atoms, and (ii) a diacid component comprising residues of dicarboxylic acids having 4 to 12 carbon atoms. These polyester-based films are particularly useful for preparing ultra-thin LCD or OLED polarizers, because they can be stretched very thin with a high stretch ratio at lower temperatures.
