Patents for accelerated degradation or controlled degradation of biopolymers
Use of an additive composition for the controlled accelerated decomposition of condensation polymers
Patent profile:
The invention relates to the use of a mixture consisting of at least one aliphatic or cycloaliphatic polyol, in particular one adlitol or cyclitol, and at least one organic phosphorus compound under protic conditions as an additive (hydrolysis catalyst) that catalyzes the hydrolysis of condensation polymers. The invention also relates to a condensation polymer composition which contains at least one aliphatic or cycloaliphatic polyol, in particular one adlitol and/or cyclitol, at least one organic phosphorus compound and at least one condensation polymer. Another aspect of the invention is a molding compound or a molded part that can be produced from the condensation polymer composition according to the invention. Finally, the invention is directed to a method for producing the condensation polymer composition.
Benefits for potential applications:
- Efficient chemical recycling
- Accelerated hydrolysis of polyester and nylon waste
- Significantly shorter process times & lower energy consumption
- Easy integration into existing processes
- Additive can be mixed directly into polymer blends
- Compatible with standard injection molding and extrusion
- Sustainability & environmental friendliness
- No heavy metal catalysts required– Process is harmless to health and beneficial to the environment
- Contributes to the circular economy: plastics can be recycled more easily and more frequently
- Cost savings
- Reduced energy consumption due to lower activation energy
- Fewer heating/cooling cycles, less need for post-treatment and disposal
- Flexibility & Product Diversity
- Hydrolysis rates adjustable by selecting polyol/phosphorus components
- Wide range of applications for resulting molding compounds and components
- Future-proof & Scalable
- Chemically clearly defined additives → consistent quality
- Easily scalable from laboratory to industrial production
