Solution Overview
Problem
Conventional polymer synthesis processes face inefficiencies due to batch reactor limitations, where reactants and products cannot be continuously fed and discharged, and struggle to produce polymers with specific molecular weights, which is crucial for controlling polymer properties.
Innovation Solution
A molecular weight-adjustable polymer synthesis process that continuously feeds gaseous monomers, surfactants, and initiators, with the initiator flow rate inversely proportional to the polymer's molecular weight, allowing for simultaneous and continuous reaction and product discharge, and uses liquid-gas separation and centrifugation for purification.

Engineering Contradiction Analysis
1Productivity
If a batch reactor is used for polymer synthesis, then monomer conversion rate is excellent, but production efficiency is low because reactants cannot be continuously fed and products cannot be continuously discharged
Solution Approach 1:
The patent applies continuous flow reactor technology to replace batch reactors, enabling continuous feeding of monomers and initiators and continuous discharge of polymer products. This continuous operation eliminates idle time between batches and maintains constant reaction conditions, thereby significantly improving production efficiency while reducing overall reaction time
Solution Approach 2:
The patent uses adjustable flow rates for feeding monomers and initiators in the continuous reactor system. By dynamically controlling the flow rates, the system can optimize reaction conditions and productivity while maintaining excellent monomer conversion rates, resolving the contradiction between production efficiency and reaction time
2Manufacturing precision
If conventional polymer synthesis is performed, then polymer is produced, but molecular weight control is difficult due to chain reaction characteristics
Solution Approach 1:
The patent employs parameter control in continuous flow reactors, specifically controlling the flow rates of monomers and initiators, temperature, and pressure to precisely regulate polymer molecular weight. The continuous flow system allows for stable and reproducible parameter control, achieving desired molecular weight precision without excessive process complexity
Solution Approach 2:
The patent implements online monitoring and feedback control of reaction parameters in the continuous flow system. By continuously monitoring molecular weight and adjusting feed rates accordingly, the system achieves precise molecular weight control while maintaining manageable process complexity through automated feedback mechanisms
