Abstract: PURPOSE:To provide superior antistatic properties and duration thereof and also ease of adhesion, coloring properties, ultraviolet radiation screening properties, and the like by incorporating a compound shown by formula I in one surface layer of a fluororesin film having a laminated structure of two or more layers. CONSTITUTION:A laminated fluororesin film having a laminated structure of at least two layers can be functionally improved by having that of three, four, five, or more layers. However, a two- or three-layer laminated structure is found to be more desirable by totally taking a production technique, a quality, a profitability, and others into consideration. A two-layer structure containing a compound shown by a formula I in either layer is most desirable. In the formula I, Ar is aromatic group which may have substituent; (n) is an integer of 1-5; and X is OM (M is hydrogen or salt).

Abstract: PURPOSE:To obtain a method of estimating a degree of deterioration in a PPS molded product placed in a system isolated without taking the molded product outside and moreover. without any destructive testing. CONSTITUTION:In a system where a polyphenylene sulfide molded product exists, the amount of at least one gas selected from among COk, SOl, and NmOn (k is 1 or 2, l, 2 or 3, m, 1 or 2 and n, 1 or 2) and lower aliphatic hydrocarbon generated from the system is measured to estimate deterioration in the polyphenylene sulfide molded product.

Abstract: PURPOSE:To obtain a polyester having a stabilized amount and particle diameter of contained particles by carrying out transesterification then adding a phosphorus compound and an alkali metallic compound, further adding an alkaline earth metallic compound and performing polycondensation. CONSTITUTION:An ester-forming derivative of terephthalic acid and ethylene glycol are subjected to transesterification and a phosphorus compound and an alkali metallic compound are then added to the reaction product. An alkaline earth metallic compound is subsequently added to carry out polycondensing reaction. Thereby, a polyester in which main constituent units are ethylene terephthalate is obtained.
