Synthesis and characterization of cardo co polyester of 9,9' -bis( 4-hydroxy phenyl) anthrone-10 and 1,1'-bis(R,4-hydroxy phenyl) cyclohexane with terephthaloyl chloride

Abstract

Cardo copolyesters of (50 : 50 mole compositions) 9,9'-bis(4-hydroxy phenyl) anthrone-10 and 1,1'-bis (R,4-hydroxy phenyl) cyclohexane with terephthaloyl chloride (CP-1: R = H and CP-2 : R = CH 3 ) have been synthesized byinterfacial polycondensation technique by using water-chloroform as an interphase, alkali as an acid acceptor and sodium lauryl sulfate and benzyl dimethyl hexadecyl ammonium chloride as mixed emulsifiers at 0°C for 4 h. Cardo copolyesters are characterized by IR and NMR spectral data, viscosity, chemical resistance and density. CP-1 and CP-2 possess excellent solubility in common solvents and hydrolytic stability and good thermal stability (345-350°C).
