Abstract

PROCEDURE FOR PREPARING A RAPID CRYSTALLIZATION POLYESTER COMPOSITION. A IONIZABLE METALLIC SALT, LIKE SODIUM SALT, OF AN ORGANIC COMPOUND WITH AT LEAST AN ACID PROTON OF FORMULA (M), WHERE R IS A SIMPLE, FUSED AROMATIC RING, IS REACTIONED AT A TEMPERATURE HIGHER THAN THE POLYESTER MELTING POINT. O MULTIPLE, X IS A DIRECT LINK OR A GROUP OF FORMULA (II) OR (III), A IS A CARBOXYLIC ACID GROUP, "N" IS AN INTEGER FROM 1 TO 4 "M" IS INTEGRAL AND AT LEAST 1, WITH A POLYESTER. SALT MUST HAVE A CONCENTRATION SUCH THAT CONVERTS AT LEAST 4 PERCENT OF THE FINAL GROUPS OF POLYESTER INTO CARBOXYLATE GROUPS. NUCLEATING AGENTS AND A FIBROUS LOAD CAN BE ADDED. THERE ARE DIFFERENT COMPOSITIONS AND ADDITIVES. THESE COMPOSITIONS ARE APPLICABLE TO MOLDING ITEMS. R- (X) N- (DELTA) M (I) -CH = CH- (II) -CH2- (III) (Machine-translation by Google Translate, not legally binding)
