摘要： THIS INVENTION RELATES TO A THERMOSTABILIZED LINEAR POLYESTER OR COPOLYESTER CONTAINING CALCIUM ACETATE AND PHOSPHOROUS ACID IN A MOLAR RATIO IN THE RANGE OF 1:(0.1 TO 0.8) AND AT LEAST ONE ADDITIONAL PHOSPHORUS-CONTAINING STABILIZER. THE QUANTITY OF THE PHOSPHOROUS ACID IS IN THE RANGE OF 0.005 TO 1 PERCENT BY WEIGHT AND THE QUANTITY OF THE ADDITIONAL PHOSPHORUS-CONTAINING STABILIZER IS IN THE RANGE OF 0.001 TO 5 PERCENT BY WEIGHT, BOTH CALCULATED ON THE QUANTITY OF THE DIESTER COMPONENT EMPLOYED.

摘要： This invention relates to a thermostabilized linear polyester or copolyester containing 0.001 to 5 percent by weight, calculated on the weight of the diester component employed, of a stabilizer having the formula

WHEREIN A, B, AND C ARE INTEGERS BETWEEN 1 AND 5, PREFERABLY 1 TO 3, X is a straight-chain or branched-chain or cyclic saturated hydrocarbon group having not in excess of 10, preferably one to four, carbon atoms, particularly methyl or tert. -butyl groups, or an aromatic group, particularly a phenyl group.

摘要： THIS INVENTION RELATES TO A PLANAR, DIMENSIONALLY STABLE POLYETHYLENE TEREPHTHALATE FILM AND A PROCESS FOR THE PRODUCTION OF THE SAID PLANAR, DIMENSIONALLY STABLE POLYETHYLENE TEREPHTHALATE FILM WHICH COMPRISES STRETCHING AN AMORPHOUS POLYETHYLENE TEREPHTHALATE FILM, HAVING A MEAN MOLECULAR WEIGHT LESS THAN 13,500, BY AT LEAST 200 PERCENT IN ORTHOGONAL DIRECTIONS OF THE FILM PLANE AT A TEMPERATURE IN THE RANGE OF 85 TO 95*C., WITH A FORCE OF NOT MORE THAN 0.5 KG./MM.2, AND THEN HEATING THE FILM UNDER TENSION TO A TEMPERATURE OF AT LEAST 200*C. FOR AT LEAST FIVE SECONDS.
