Abstract

PURPOSE:To obtain the titled polymer of high surface hardness, useful for molded articles etc., by irradiating electron beams on an aromatic polycarbonate polymer prepared by carbonate linkage of 2,2-bis-(4-hydroxy-3-methylphenyl) propane. CONSTITUTION:First, 2,2-bis-(4-hydroxy-3-methylphenyl)propane and diphenyl carbonate are melted by heating in an inert gas atmosphere followed by adding potassium boron hydride as the catalyst for conversion into carbonate, to the melt to carry out polycondensation by heating under reduced pressure. Thence, the resultant polymer is taken out under an inert gas atmosphere and cooled. This polymer is then made into a pressed sheet through e.g. hot press quenching process followed by electron beam irradiation on this sheet, thus obtaining the objective polymer of formula (n is degree of polymerization).
