POLYESTER RESIN, METHOD FOR PREPARING SAME, AND RESIN MOLDED PRODUCT FORMED THEREFROM
The present invention relates to a polyester resin. The polyester resin contains a particular content of diol moieties, derived from isosorbide and diethylene glycol, and thus can provide a resin molded product exhibiting high transparency in spite of a large wall thickness thereof.
Use of polyesters having inherent flame protection in adhesives and sealants
The present invention relates to the use of polyesters with inherent flame retardancy as or in adhesives, sealants and coatings, to polyesters with inherent flame retardancy and to processes for production thereof.

METHOD FOR PRODUCING A PET STARTING MATERIAL THAT IS SUITABLE FOR USE IN AN EXTRUSION BLOW MOLDING METHOD, AND HOLLOW ARTICLE PRODUCED IN THE EXTRUSION BLOW MOLDING METHOD
The invention relates to a method for producing an EBM bottle with 0.90 to 1.5 dL/g from a bottle-grade PET post-consumer recycling flake, i.e., a recycled, post-consumer PET with a viscosity of 0.65 to 0.84 dL/g, using extrusion processes, solid state polycondensation processes, and a blowing process.
Copolyester tape
Provided is a tape including a composition having a copolyester including polymeric units derived from ethylene glycol and terephthalic acid or a diester thereof and >0.50 and <5.00 wt % of polymeric units with regard to the total weight of the polyester derived from an oligomeric dihydroxy compound having a number average molecular weight of >500 g/mol and <5000 g/mol. Such tape has an improved tensile-impact strength and a reduced proneness to splitting during weaving.

POLYETHYLENE FURANOATE, HIGHLY-VISCOUS POLYETHYLENE FURANOATE MANUFACTURING METHOD, POLYESTER COMPOSITION, POLYESTER BOTTLE, POLYESTER BOTTLE MANUFACTURING METHOD, AND BEVERAGE PRODUCT
This polyethylene furanoate has an intrinsic viscosity of 0.95 - 1.50 dl/g. Said intrinsic viscosity is measured (the Huggins constant is defined as 0.32) at 30° C. by using an Ubbelohde viscometer, after dissolving 0.25 g of the polyethylene furanoate in 50 ml of a solvent mixture of phenol/1,1,2,2-tetrachloroethane = 50/50 (weight ratio).
POLYESTER POWDERS AND THE USE THEREOF IN THREE-DIMENSIONAL PRINTING PROCESSES
The present invention is directed to polyester powders suitable for use in 3D printing processes, methods of using such polyester powders in 3D printing processes, and processes for the manufacturing thereof. The polyester powders prepared in accordance with the present invention are easily recycled after such polyester powders have been subjected to 3D printing conditions. In addition, the present invention is directed to recycling processes that recondition waste polyester powders into polyester powders suitable for 3D printing.
