Abstract:Anionic ring opening polymerization of ε‐caprolactam (CL) results in the formation of high molecular weight polyamide 6 (PA6) within a few minutes. The monomer conversion rate is an important characterization parameter for polymerization process as well as the end products. This paper used PA6 films with different polymerization degrees as research object for the first time, and systematically compared the performance of four methods for measuring CL conversion rate. The analytical methods were solvent extract… Show more
“…Due to the formation of the first network, L-P(BA- co -GMA) b is difficult to dissolve in deuterium reagents, so we tested the monomer conversion by the weighing method, cleaned with ethanol after polymerisation and completely removed the solvent at high temperature, and then compared with the quality of the added monomer. 45 We found that the monomer conversion rate was over 98% (Fig. S7†).…”
We propose a novel approach to harness the side reaction for the creation of a lignin-containing, sustainable, and solvent-resistant dynamic dual network using a one-pot synthesis strategy.
