摘要:
THE SOIL AND STAIN REPELLENCY OF EXTRUDED FILAMENTS OF A SYNTHETIC RESIN CAN BE IMPROVED BY INCORPORATING IN THE RESIN A SMALL AMOUNT, ABOUT 1%, OF AN AMPHIPATHIC COMPOUND HAVING FROM ONE TO FOUR FLUOROALKYL GROUPS PENDENT FROM AN ORGANIC RADICAL. THE REPELLENCY IS PROVIDED BY THE FLUOROALKYL GROUPS, WHICH TEND TO BE CONCENTRATED AT THE SURFACE OF THE FIBER.

THERMOPLASTIC COMPOSITIONS HAVING EXCELLENT INJECTION MOULDING PROPERTIES ARE OBTAINED FROM LINEAR SATURATED POLYESTERS AND ALKALI METAL SALTS OF ORGANIC PHOSPHONIC ACIDS, THE MONOESTERS THEREOF, OF ORGANIC PHOSPHONOUS ACIDS OR OF ORGANIC PHOSPHINIC ACIDS, THE ORGANIC RADICALS BEING SATURATED OR UNSATURATED ALKYL, CYCLOALKYL, ARYL, OR ARALYKYL GROUPS HAVING UP TO 15 CARBON ATOMS.

THE PREPARATION OF LINEAR HIGH-MOLECULAR WEIGHT, FILM AND FIBER FORMING POLYESTER AND COPOLYESTERS WHEREIN THE REACTION OF POLYCARBOXYLIC ACID WITH A POLYOL TAKES PLACE IN THE PRESENCE OF CUPROUS AND CUPRIC INORGANIC SALTS TO IMPROVE PROCESSING AND END PRODUCT CHARACTERISTICS.
摘要:
THERMOPLASTICALLY WORKABLE MOULDING COMPOSITIONS OF PARTICULARLY HIGH IMPACT STRENGTH, COMPRISING A MIXTURE OF SATURATED LINEAR POLYESTER WITH COPOLYMERS OF CONJUGATED ALIPHATIC DIENE AND ACRYLIC ACID ESTERS.
摘要:
IN WHICH R1 and R2 are each as defined above and p and q are each zero or a positive integer not more than 10, or blending the resultant polymer into linear fiber-forming polyesters. Process for preparing polyesters improved in dyeability with acid dyes which comprises polycondensing a dicarboxylic acid with a glycol, the whole or part of the glycol being the one represented by the formula: WHEREIN R1 and R2 are each a lower alkyl group or, when taken together, they represent a lower alkylene group, R3 is a lower alkyl group or a group of the formula:

A LINEAR TEREPHTHALATE POLYESTER FIBER OR FILM-FORMING POLYMER CONTAINING MINOR AMOUNTS OF A METALLIZED COMPOUND HAVING THE FORMULA:
Z(-O-C(-R)2-C(-R)2-C(-R)2-SO3-METAL)N
WHEREIN N IS AN INTEGER OF 1 OR 2: WHEN N=1,Z IS AN ALKYL, ARYL, ARALKYL RADICAL, SUBSTUTUTED DERIVATIVES THEREOF WHEREIN THE SUBSTITUENT IS HYDROXY, ALKYL AND ALKOXY; WHEN N=2, Z IS AN ALKYLENE, ARYLENE, ARALKYLENE RADICAL. SUBSTITUTED DERIVATIVES THEREOF WHEREIN THE SUBSTITUENT IS HYDROXY, ALKYL AND ALKOXY; AND R, INDIVIDUALLY, IS HYDROGEN OR ALKYL RADICAL CONTAINING FROM 1 TO 6 CARBON ATOMS.
