AI Technical Summary

Technical Problem

Existing polymerization methods, such as batch and dropwise polymerization, struggle to achieve uniform copolymer composition and narrow molecular weight distribution, particularly in the production of photoresist resins, leading to inconsistent quality and difficulty in controlling reaction temperature.

Method used

A method involving radical polymerization of monomer components using a microreactor with multiple introduction ports, where monomers are introduced through different ports and undergo polymerization reactions in the presence of a polymerization initiator and chain transfer agent, allowing for precise control of monomer ratios and reaction conditions to achieve uniform copolymer composition and narrow molecular weight distribution.

Benefits of technology

The method produces polymers with consistent copolymer composition and narrow molecular weight distribution, enhancing solubility in solvents and enabling precise microfabrication, particularly in semiconductor materials.

Abstract

To provide a manufacturing method of polymer for obtaining a polymer having a uniform copolymerization composition with a narrow molecular-weight distribution.SOLUTION: A manufacturing method of polymer comprises the step of radically polymerizing monomer components including two or more monomers in the presence of a polymerization initiator with use of a microreactor having a channel in which a plurality of liquids can be mixed. The microreactor comprises a first introduction port for introducing a monomer component and another introduction port located downstream the first introduction port. The monomer components are introduced into the first introduction port and the other introduction port.SELECTED DRAWING: None
