Abstract: PURPOSE:To obtain the subject composition having excellent slipperiness and giving a fiber, etc., having low void content because of excellent adhesivity and affinity of the composition to particles by carrying out ester interchange reaction, in the presence of particles having an ester-interchangeable group attached to the particle by a specific method. CONSTITUTION:Particles to be added to a polyester (preferably calcium carbonate, etc.) is surface-treated with a monophthalate ester of formula (R is 1-20C alkyl, alkylene hydroxide or polyether) to attach an ester-interchangeable functional group to the particle. The objective composition is produced by carrying out ester-interchange reaction of a dicarboxylic acid composed mainly of aromatic dicarboxylic acid or its ester-forming derivative with a glycol, and subjecting the reaction product to polycondensation reaction. The treatment of the particle can by carried out e.g. by adding a monophthalate ester to a system for the wet dispersion treatment of calcium carbonate particles.

Abstract: PROBLEM TO BE SOLVED: To provide a process for producing a microporous resin film at a low cost without steps of extracting the pore-forming substance from the resin and of recovering it, which process comprises dispersing the resin in water and removing the dispersion water from the crosslinked resin. SOLUTION: This microporous film is obtained by supplying high-pressure water or supercritical water to a molten resin in the mid course of extrusion, extruding the mixture after melt kneading into a sheet, cooling the sheet, and heating the sheet to boil off the water from the crosslinked resin sheet. The resin used is exemplified by a thermoplastic resin selected from among a polyolefin, a polyamide, a polyphenylene sulfide, a vinyl polymer, a mixture thereof, and a modification thereof and is particularly desirably a polyolefin resin. Further, the resin is desirably a water-crosslinkable resin which forms a crosslinkage when reacted with water or a special melt-extrudable olefin crosslinked resin. It is desirable that the resin is pre-mixed with a water absorbent because the pre-mix can give a microporous film having a small mean pore diameter and a sharp pore diameter distribution. It is desirable that the water used contains a surfactant.

Abstract: PROBLEM TO BE SOLVED: To perform rapid casting or uniform orienting or the like of a sheet by casting so that a holding angle between a tangential line drawn on a moving cooling medium at a contact point of a sheet with the medium and a tangential line drawn to a corresponding circle of an orbit of the sheet becomes specific. SOLUTION: A polyamide raw material obtained by mixing a liquid crystal polymer or the like with a polyesteramide or the like is dried, dehydrated, then melt extruded in a nitrogen flow or in vacuum by a melt extruder without lowering a molecular weight, ionomers are laminated on both surfaces of a polyamide resin layer, and the obtained laminated melt sheet 7 is cooled and solidified by a moving cooling medium 2. Thus, a holding angle 6 between a tangential line 4 drawn at a contact point P of a melt sheet 7 extruded from a mouth 1 and the medium 2 and a tangential line 5 drawn at a point P of an imaginary corresponding circle 3 including as many locusses of the melts as possible exceeds 0 degree. Before the sheet 7 is brought into contact with the medium 2, a water membrane or static charge is formed on the medium 2, the sheet 7 is brought into contact with a drum and quenched. Thus, rapid casting can be achieved, and excellent homogeneity of a thickness of and stretchability of the film can be obtained.
