Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Acrylic acid derivatives are unstable against external stimuli such as heat, light, and oxygen, leading to easy polymerization into oligomers or polymers.
Innovation Solution
A composition comprising at least 90% (w/w) of a compound of formula (I) with R3 being C1-4-alkyl and C1-6-alcohol, which stabilizes the acrylic acid derivative by ensuring coexistence with alcohol, preventing polymerization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If acrylic acid derivative is stored or processed under external stimuli (heat, light, oxygen), then polymerization reaction occurs easily forming oligomers or polymers, but the derivative loses its stability and becomes unusable
Solution Approach 1:
The patent introduces a polymerization inhibitor as an intermediary substance that mediates between the acrylic acid derivative and external stimuli (heat, light, oxygen). The inhibitor preferentially reacts with free radicals generated by external stimuli, preventing them from initiating polymerization of the acrylic acid derivative. This allows the derivative to maintain stability during storage and processing without requiring complete isolation from environmental factors.
2Reliability
If polymerization inhibitor is added to stabilize acrylic acid derivative, then stability against polymerization is improved, but the composition becomes more complex with additional components
Solution Approach 1:
The patent optimizes the concentration parameter of the polymerization inhibitor within a specific range (0.01-5 wt%, preferably 0.1-1 wt%) to achieve effective stabilization while minimizing composition complexity. By precisely controlling the inhibitor concentration, the patent finds an optimal balance where sufficient stability is provided without excessive amounts of additional components, thus maintaining relative simplicity of the overall composition.
