Notes:
A series of polyarylates having inherent viscosities of 0.4-1.1 dL/g was prepared by the two phase polycondensation of 1,1,3-trimethyl-3-(4-chloroformylphenyl)indanecarbonyl chloride with various bisphenols in an organic solvent-aqueous alkaline solution system in the presence of a phase transfer catalyst. Similarly, copolyarylates of high molecular weights were prepared from a mixture of the phenylindanedicarbonyl chloride, terephthaloyl chloride, and 2,2-bis(4-hydroxy-phenyl)propane. All the polyarylates were characterized by their amorphous nature and high solubility in organic solvents. They gave transparent and tough films by the solution casting. The films had tensile strength of 33-46 MPa, elongation at break of 3-16%, and tensile modulus of 1.2-1.6 GPa. These polyarylates had glass transition temperatures in the range of 205-310°C, and began to decompose at ca. 350°C in air.
