Abstract: PURPOSE:To obtain a polyester excellent in slidability, surface smoothness and abrasion resistance, by reacting a bifunctional acid component based on an aromatic dicarboxylic acid (functional derivative) with a glycol component in the presence of specified CaCO3 particles. CONSTITUTION:CaCO3 and 0.002-5wt% (in terms of P2O5) P are dispersed in a glycol such as ethylene glycol by means of, e.g., a high-speed disperser or a colloid mill and filtered to obtain CaCO3 particles having a geometric- means diameter (dg) of 0.02-2.0mum and a geometric standard deviation (deltag) of 2.0-3.5. A bifunctional acid component based on an aromatic dicarboxylic acid or its functional derivative [e.g., terephthalic acid (alkyl ester)] is reacted with a glycol component based on ethylene glycol in the presence of a catalyst and 0.001-5wt%, based on the formed polyester, said CaCO3 particles.

Abstract: PURPOSE:To improve the moldability of a polyester and the surface evenness, slipperiness, etc., of moldings, by adding a bifunctional org. compd. having a long-chain alkyl group and a hydroxyl, carboxyl or amino group to the polyester. CONSTITUTION:A bifunctional org. compd. having two functional groups selected from the group consisting of -OH, -COOR and -NHR (wherein R is H or an alkyl group- and a 6 C or higher long-chain alkyl group (e.g. 1,2-eicosanedial, 4-octadecylresorcinol) is prepd. The org. compd. is added to a polyester (e.g., polyethylene terephthalate) to obtain a desired polyester compsn. The addition is made before the completion of the polycondensation reaction in the production of the polyester to thereby react it sufficiently with a polyester component. The resultant polyester compsn. is suitable for use in the production of magnetic tapes.

Abstract: PURPOSE:To obtain a particle slurry finely dispersible in a polyester without forming coarse agglomerated particles, by dispersing inorganic compound particles in glycol using a phosphorus compound, and ammonia or a lower amine compound as dispersing agents. CONSTITUTION:In preparing a particle slurry by dispersing inorganic compound particles with an average primary particle diameter of 10mu or less in glycol, a phosphorus compound, and ammonia or a lower amine compound is used as dispersing agents. Inorganic compound particles to be used are preferably an oxide or a carbonate, especially calcium carbonate. When inorganic compound particles with an average primary particle diameter of above 10mu are applied to a polyester, they may cause yarn breakage or, may cause coarse protuberance in a film, which are undesirable.
