Transparent polyamide

Abstract

Particular polymers, polymer compositions, and methods for producing polymers or polymer compositions are described herein.

Description

[0001] Polymers such as polyamides are used in several applications, for example for clothing, fuses and plugs. Therefore, the demand for polyamides comprising a recycling or biobased content is steadily increasing. Furthermore, in many of these applications, the polyamides comprise a reinforcement such as a fiber to make the polyamide more elastic. A side effect of the addition of the reinforcement is that the polyamide becomes opaque and, therefore, the optical properties of the polyamide have hitherto played only a minor role. However, it is also possible to use polyamides in transparent applications, for example for lenses or windows. Therefore, it is an object of the present invention to provide a polymer comprising:

[0002] - improved thermal stability

[0003] - improved optical properties

[0004] - improved mechanical properties

[0005] - improved chemical resistance

[0006] - low water absorption, and / or

[0007] - improved sustainability.

[0008] This object is at least partially achieved by a polymer obtainable by or by polymerizing a mixture comprising monomers A, B and C:

[0009] wherein monomer A is a monomer of formula (1):

[0018] or a derivative thereof,

[0019] wherein o is selected from 1 or more and 18 or less, and

[0138] Mass-average molar mass (Mw): An Agilent 1100 series integrated instrument was used, comprising 2 x PL HFIP gel 300x7.5 mm + 1 HFIP-LG Guard 50x7.5 mm and a DRI Agilent 1100 detector. All calibrations were performed using PMMA standards with molecular weights between 800 g / mol and 2,200,000 g / mol, purchased from Polymer Standards Service. The flow rate was 1 mL / min, and the sample concentration was 1.5 mg / mL. The eluent was HFIP + 0.05% potassium trifluoroacetate.

[0139] Preferably, the content of amino-terminal groups and / or carboxyl-terminal groups is obtained as follows: To determine the content of amino-terminal groups (AEG), the sample (1 g) is dissolved in a phenol-methanol mixture (volume ratio 75:25 v / v; 30 mL) at 85 °C, followed by potentiometric titration with 0.02 mol / L HCl (pH electrode detection). To determine the content of carboxyl-terminal groups (CEG), the sample is dissolved in 30 mL of benzyl alcohol and titrated with 0.05 N alcohol KOH (visual inspection).

[0140] According to ISO 307, relative viscosity (RV) is determined by measuring the viscosity of a 1g sample in a 100mL solution using an UBBE Lohde viscometer at 20°C. A 1:1 mixture of phenol and o-dichlorobenzene is used as the solvent. Relative viscosity is the coefficient between the viscosity of the solution and the viscosity of the phenol / o-dichlorobenzene PODC mixture.

[0141] According to ASTM D 1003, use 10x10x2mm. 3 The test specimen (patch) measures transmittance, haze, and clarity.

[0142] Young's modulus and elongation at break were determined by tensile testing according to ISO 527-2:2012, and Charpy impact test (Charpy) was determined according to ISO 179-2:2012 at 23°C and -30°C using injection-molded samples of the corresponding materials.

[0143] Chemical resistance to CaCl2 was determined as follows: Deionized water (100 mL) and ethanol (100 mL) were mixed in a 1:1 (v:v) ratio. CaCl2 (76.6 g) was added with stirring, and the mixture was cooled to room temperature over 24 hours with stirring. Subsequently, a sample (100 × 100 × 2 mm) was prepared. 3 The sample was partially immersed in the solution for 30 minutes. Then, it was washed with deionized water and allowed to dry under ambient conditions. The sample surface was then visually inspected by comparing the exposed half of the sample with the unexposed half. If no difference was observed, the sample exhibited chemical resistance to CaCl2. If any difference was observed, the sample did not exhibit chemical resistance to CaCl2.

Example

[0293] The present invention is further illustrated by the following embodiments.

[0294] General procedure: A mixture (about 2 to 4 kg, preferably 2.8 kg) of monomers (e.g., monomers A, B, and C) and water (about 10% by weight of all monomers) is placed in a pre-dried 7.8 L autoclave and purged 10 times with dry nitrogen. The monomer ratio is adjusted so that the amounts of acid groups and amino groups in the mixture are equal, for example, 1 mol of diacid and 1 mol of diamine. The mixture is then heated to 240 °C and continuously stirred under pressure. After 60 min, the pressure is released over 120 min at 260 °C (internal temperature of 240 °C). The temperature is then maintained constant at 260 °C for 90 min to obtain the polymer. Further details are available in Example 2.
