Embodiment 5

[0262] Embodiment 5: prepare polyoxalic acid / isosorbide fatty acid polyester by polymerizing oxalic acid ester, isosorbide and fatty acid ester Ester Copolymer

Embodiment 2

[0263] Embodiment 2 is carried out according to Example 1, and the difference is that 11.46g isosorbide (hereinafter abbreviated as ISO, 78.37mmol), 15.03g diphenyl oxalate (hereinafter abbreviated as DPO, 62.03mmol), 4.99g fatty acid diphenyl (4-Methylphenyl) ester (hereinafter abbreviated as DMPA, 15.28mmol), 7.5mg Irganox 1010 (an antioxidant) and 7.3mg HostanoxPEPQ (another antioxidant) into a 100 milliliter (mL) glass reactor .

[0264] The resulting polyester copolymer contained 19.1 mole % fatty acid ester monomer in the polyester copolymer and had Tg, Mw, Mn and polydispersity index as shown in Table I.

Embodiment 7

[0268] Example 7: Prepare polyoxalic acid / isosorbide fatty acid poly Ester Copolymer .

[0269] Weigh 14.69 grams (g) of isosorbide (hereinafter abbreviated as ISO, 100.48mmol), 15.11g of diphenyl oxalate (hereinafter abbreviated as DPO, 62.36mmol), 7.55g of divinyl fatty acid (hereinafter abbreviated as DVA, 38.10 mmol), 9.2mg Irganox 1010 (an antioxidant) and 11.4mg Hostanox PEPQ (another antioxidant) into a 100mL glass reactor equipped with a mechanical stirrer, nitrogen inlet and a distillation head connected to the condenser and a collection Receiver for condensed product. The glass reactor was heated by an oil bath.

[0270] The reactor contents were heated under a nitrogen atmosphere until the contents melted. Once a clear mixture was obtained at 155°C, 2.1 mg n-butyltin hydroxide (0.01 mmol) in toluene solution was added as catalyst. The reactor contents were then further heated until the temperature reached 195°C (here it was assumed that the temperature of the...

Abstract

A polyester copolymer, having a number average molecular weight of equal to or more than 4000 grams / mole and having a glass transition temperature of less than 160 DEG C, containing: (a) in the rangefrom equal to or more than 45 mole % to equal to or less than 50 mole %, based on the total amount of moles of monomer units within the polyester copolymer, of one or more bicyclic diol monomer units,wherein such one or more bicyclic diol monomer units is / are derived from one or more bicyclic diols chosen from the group consisting of isosorbide, isoidide, isomannide, 2,3:4,5-di-O-methylene-galactitol and 2,4:3,5-di-O-methylene-D-mannitol; (b) in the range from equal to or more than 25 mole % to equal to or less than 49.9 mole %, based on the total amount of moles of monomer units within the polyester copolymer, of an oxalate monomer unit; (c) in the range from equal to or more than 0.1 mole % to equal to or less than 25 mole %, based on the total amount of moles of monomer units within the polyester copolymer, of one or more linear C3-C12 dicarboxylate monomer units; and (d) optionally equal to or more than 0 mole % to equal to or less than 5 mole %, based on the total amount of molesof monomer units within the polyester copolymer, of one or more additional monomer units. A process for producing such a polyester copolymer, a composition containing such polyester copolymer, a method for manufacturing an article comprising the use of one or more of such polyester copolymers and an article obtained or obtainable by such a method.

Description

technical field [0001] The present invention relates to novel polyester copolymers, methods for producing polyester copolymers, compositions comprising polyester copolymers, methods of using polyester copolymers for the manufacture of articles and articles obtained or obtainable by such methods. Background technique [0002] In recent years, the trend has developed to obtain various chemical products from sustainable resources. Polymers and monomers make up a significant portion of the chemicals produced in the world today, with approximately 80% of bulk chemicals being monomers or monomer precursors. They therefore play a central role in the transition to a sustainable chemical industry. Today, most polymers are produced from fossil fuel raw materials, which after use (by incineration or degradation) rise to significant greenhouse gas emissions on a global scale. The development of so-called sustainable (preferably partially or fully bio-based) polymers can make an import...
