“…In contrast, 6 was obtained in high yield and had a high molecular weight. This was because 6 is more organosoluble than 4 and 5 , because of the high flexibility of the methoxy groups 16–25. Alkoxy groups can add good solubility to aromatic polymer such as poly(phenylenemethylene) 26, 27.…”

“…These results, although imperfect, have stimulated our interest in the development of a novel method to produce high‐molecular weight heteroatom‐containing novolacs without the formation of by‐products. In our previous study, we showed that chloroform is an effective medium for the preparation of high‐molecular weight novolacs 43, 44. Therefore, we hypothesized that it would be possible to prepare diphenyl oxide‐ and diphenyl sulfide‐based novolacs with high‐molecular weights using chloroform.…”

“…Being a natural polymer‐based plastic, LP is considered to be a substitute for commodity polymers derived from fossil fuels. We have been studying the manufacturing procedure and the applications of organosoluble phenolic resins derived from phenol derivatives and aldehydes and the advantages of these organosoluble phenolic resins over artificial phenolic resins 36–51. By developing novel LP‐based materials, it may be possible to reduce the consumption of fossil fuels and recycle valuable industrial materials from waste.…”
