Title:
POLYMER PRODUCTION METHOD
Document Type and Number:
WIPO Patent Application WO/2021/250920
Kind Code:
A1
Abstract:
Provided is a novel polymer production method by which various monomers can be efficiently reacted. This polymer production method comprises a step for irradiating, with electromagnetic waves, a mixed liquid containing a monomer, a polymerization initiator, and a solvent to ion-polymerize the monomer. The frequency of the electromagnetic waves is 1-1,000 MHz, and is a frequency at which: the dielectric loss tangent measured by a probe method is less than 0.05 when only the solvent is irradiated with the electromagnetic waves; and the dielectric loss tangent measured by the probe method is at least 0.05 when the mixed liquid is irradiated with the electromagnetic waves.
