"Copoliu00e9ster, composition of copoliu00e9ster, pelu00eccula, molded container, and process for preparing umcopoliu00e9ster".The invention relates to copoliu00e9ster having umaviscosidade inherent ranging from about 0.4 to about 1.4 DL / Ge a crystallisation temperature cold ranging from about 120 160 198 C.These include the product dereau00e7u00e3o copolyester component containing a glycol of about 85 to about 100% by mol of 1,3 - propanediol.A component of u00e1cidodibu00e1sico comprising about 85 to 100% in the mold a dibasic acid selected from terephthalic acid, anhydrides, acid chlorides, acidonaftalenodicarboxu00edlico,And its u00e9steresde lower alkyl, and mixtures thereof, and from about 5 to about 15% by mol of a comonomer.The presence of the comonu00f3meroreduz the crystallisation temperature of copolyester of acordocom invention, so that pre forms can serfacilmente molded of amorphous copolyester.Such pre forms amorfassu00e3o easily molded by filling the breath in bottles or other settings of the containers,Or they may be moldadaspor injection into various shapes of objects, or extruded empelu00edculas or leaves.Consequ00b3entemente, in another form, ainvenu00e7u00e3o relates to films and containers prepared dacomposiu00e7u00e3o of copoliu00e9ster described above.The film erecipientes according to the invention possess properties debarreira gas improved, so that they can serusados for storing perishable goods, such comobebidas,Food and cosmetics.
