Abstract:

Novolac resins were prepared from p-chlorophenol using a variety of sources for methylene bridges. Alkaline and acidic catalysts were used to promote condensations however, the products obtained were not always true novolacs in that polyhydroxybenzyl ethers and polyhydroxybenzylamines were isolated. Molecular weights varied from that of the dimer to 1500 for the true novolacs and as high as 1975 for the polyhydroxybenzyl ethers. Dechlorination of the various resin species was successful. Polyglycidyl ethers epoxy resins were formed from several species of the resins. Author
