| titleOfInvention | Amorphous polyester chip and method for production thereof, and method for storage of amorphous polyester chip |
| abstract | The amorphous polyester chip of the present invention isncharacterized by a moisture content of not more than 300 ppmnand a fine particle content of not more than 500 ppm.nAccording to the amorphous polyester chip of the presentninvention, a formed product having a uniform polymerncomposition can be produced with superior processingnoperability. n As one preferable embodiment of the chip, an amorphousnpolyester chip which is a copolymerized polyester chipncomprising a main repeating unit consisting of ethylenenterephthalate, and 1,4-dimethylene-cyclohexane terephthalatenor neopentyl terephthalate, wherein the glycol component ofnthe copolymerized polyester has a specific composition of 50nto 85 mol% of ethylene glycol, 12 to 45 mol% of 1,4-cyclohexanedimethanolnor neopentyl glycol and 1.5 to 7.0 mol%nof diethylene glycol, can be mentioned. With suchncopolymerized polyester chip, a formed product (particularlynfilm) having a uniform polymer composition and superior inntransparency and solvent adhesion can be achieved. n The amorphous polyester chip of the present inventionncan be obtained by a method including cooling an amorphousnpolyester obtained by melt polymerization, cutting thenpolyester to give a chip, feeding the chip in a treatment tanknof a fluidized bed type drying apparatus, passing the chipnwhile drying by flowing a dry gas, or, after drying in vacuonor by flowing a small amount of a dry gas in vacuo in a dryerndrying apparatus, transferring the chip to a fine particlenremoving apparatus without allowing contact with outside airnand removing fine particles. |
