Definitions
- Stabilizer composition use of the stabilizer composition, process for stabilizing condensation polymers against hydrolytic degradation, and hydrolysis-stabilized composition and molding or molding made therefrom
- the present invention relates to a novel stabilizer composition based on an aziridine and at least one hydrotalcite, zeolite, dawsonite or mixtures thereof.
- the stabilizer composition is suitable for stabilizing condensation polymers, in particular aliphatic polyesters, against hydrolytic degradation.
- the invention also relates to the use of the stabilizer composition according to the invention and to a method for stabilizing condensation polymers against hydrolytic degradation.
- the present invention relates to moldings and moldings that can be produced from the composition according to the invention.
- Polycondensation polymers such as polyesters, polyamides and polycarbonates are generally classified as hydrolysis-sensitive polymers, since the chemical bonds of these polymers can be broken by water. This can be advantageous for degradation of these polymers, for example in the environment, but is also often a disadvantage, particularly in the case of technical applications and desired extended useful lives.
- Polymers from fossil raw materials are increasingly being replaced by polymers from renewable raw materials.
- These "bio" polymers are, for example, based on aliphatic polyesters such as polylactic acid, also referred to as polylactide or PLA.
- aliphatic ester groups are significantly more sensitive to hydrolysis than (partly) aromatic ester groups (see, for example, M. Dröscher et al, Angewandte Makromolecular Chemistry 1984, 128, 203-213).
- WO 2012 072 489 mentions carbodiimides, polycarbodiimides, epoxides, alkyl ketene dimers and oxazolidinones as hydrolysis stabilizers.
- CN 101 759 969 describes hydrolysis-resistant PLA-based compositions which contain carbodiimides, epoxy, oxoazolines, oxazines or aziridines.
- Compositions are also known, for example from WO 94/24201, which contain further additives such as calcium oxide or calcium silicates in addition to the hydrolysis stabilizer in the form of epoxides.
- drilling fluids which can contain aziridines, hydrotalcites and degradable polymers (WO2015/065575).
- Polycondensates containing aziridines are therefore to be regarded as the closest prior art.
- aziridines in polyesters and PLA is mentioned in US 3959228, in TW 1472575, in US 2014/0100318 or US 2016/024297.
- Patent claim 9 specifies possible uses of the stabilizer composition
- patent claim 10 relates to a method for stabilizing condensation polymers against hydrolytic degradation
- Patent claim 13 relates to a hydrolysis-stabilized composition
- patent claim 17 to a molded part or a molded body that can be produced from the hydrolysis-stabilized composition.
- the present invention thus relates to a stabilizer composition consisting of at least one aziridine and at least one hydrotalcite, zeolite, dawsonite or mixtures thereof.
- polyesters with combinations of aziridines with hydrotalcites, zeolites or dawsonite have particularly good hydrolytic stability. These combinations have not previously been described in the literature.
- New hydrolysis-stabilized plastic compositions made from polycondensation polymers such as polyesters or polyamides, as well as new stabilizer compositions for improving the hydrolytic stability with high effectiveness, particularly in the case of biopolymers such as PLA, are made available.
