Cardanol -aldehyde ferric polymers were prepared by condensation polymerization with formaldehyde, n-butyl aldehyde, furfural and iron trichloride.
In condensation polymerization, the monomer will affect the purity of the molar ratio of functional groups, so that the molecular weight deviates from the set value.
They are usually prepared from equivalent amounts of glycols and dibasic carboxylic acids, which undergo condensation polymerization to produce the polyester and water.
