Solution Overview
Problem
Fluorine-containing monomers are prone to decomposition and polymerization during storage, making it challenging to stabilize them effectively for use in producing fluorine-containing polymers.
Innovation Solution
A composition comprising a fluorine-containing monomer and a polycyclic aromatic compound is used, where the polycyclic aromatic compound limits the decomposition and polymerization of the fluorine-containing monomer, allowing for simpler storage and separation, and enabling the production of a more stable fluorine-containing polymer.

Engineering Contradiction Analysis
1Duration of action of stationary object
If fluorine-containing monomer is stored for use in polymer production, then the monomer can be used for manufacturing fluorine-containing polymers, but the monomer undergoes decomposition and polymerization during storage
Solution Approach 1:
A phenolic compound is introduced as an intermediary stabilizer that interacts with the fluorine-containing monomer to prevent decomposition and polymerization. The phenolic compound acts as a mediator between the monomer and environmental factors, providing stability during storage without interfering with subsequent polymerization reactions.
Solution Approach 2:
The storage conditions are modified by changing the chemical environment through addition of phenolic compounds. This parameter change (chemical composition) transforms the storage system from one that causes decomposition to one that maintains monomer stability over extended periods.
2Ease of manufacture
If distillation is used to separate fluorine-containing monomer from stabilizer, then separation can be achieved, but the production process becomes complex and costly
Solution Approach 1:
The phenolic compound serves as a disposable stabilizer that is intentionally left in the system during storage and processing. Rather than requiring complete removal through complex distillation, the stabilizer is designed to be easily separated or remain as a non-interfering residue, simplifying the overall manufacturing process.
Solution Approach 2:
The invention changes the physical or chemical parameters of the stabilizer (such as volatility, solubility, or reactivity) to enable simpler separation methods. This parameter modification allows separation through less complex means than traditional distillation, reducing device complexity and manufacturing costs.
3Stability of the object's composition
If fluorine-containing monomer is stored at low temperatures to improve stability, then decomposition is reduced, but storage and handling becomes more complex
Solution Approach 1:
The phenolic compound acts as a chemical intermediary that provides stability at ambient temperatures, eliminating the need for complex low-temperature storage systems. The stabilizer mediates the interaction between the monomer and thermal energy, allowing stable storage under simpler conditions.
Solution Approach 2:
The invention changes the stability parameter of the monomer system by adding phenolic compounds, which allows the monomer to maintain stability at higher temperatures. This parameter change eliminates the need for complex cold storage infrastructure, simplifying the storage system.
