Abstract
PURPOSE: To provide an elongated film or sheet-like material prepared from poly- 1,3-phenylene terephthalate, excellent in heat-resistant characteristic, mechanical characteristic and flame retarding property, and suitable for electric insulation, magnetic tape, photograph film, and metal deposited film.
CONSTITUTION: (i) Terephthalic acid or its derivative, and (ii) resocine or its derivative, are condensed to obtain poly-1,3-phenylene terephthalate (A). With the above terephthalate (A) are blended a nucleic agent, an inorganic filler, a lubricant and the like to form a film or a sheet-like material by compression molding, extrusion molding or the like. Then, the film or the like is elongated (including blow molding) in uniaxially or biaxially to obtain the subject elongated film or sheet- like material. The above condensation can be performed by an ordinary process for producing polyesters such as (a) a process for performing polycondensation in a molten state or a solution state, (b) a process for performing polycondensation by an interface process, or the like process.
