Synthesis and physico‐chemical properties of poly[4‐(1,1,3,3‐tetramethylbutyl)phenyl methacrylate]

Abstract

Abstract Poly[4‐(1,1,3,3‐tetramethylbutyl)phenyl methacrylate] ( 1a ) was synthesized and its physicochemical properties were determined in the condensed phase and in dilute solution. The polymerization of 4‐(1,1,3,3‐tetramethylbutyl)phenyl methacrylate was carried out by radical mechanism in solution with 2,2′‐azoisobutyronitrile as initiator. Several samples were characterized by their intrinsic viscosity, by osmometric measurements, differential scanning calorimetry, and X‐ray diffraction. The viscometric behaviour of fractions of 1a was studied in good solvents and theta solvents, and the conformational parameters were calculated. Polymer 1a presents an unusual high rigidity in the chain. X‐Ray diffraction of this polymer indicates a one‐dimensional ordering of a mesomorphic type.
