Verfahren zur Herstellung von polymerisierten Kohlensaeureesterderivaten

New polycarbonates are made by condensing a carbonic acid derivative with a 1:3-cyclobutanediol having the formula where R1, R2, R3 and R4 are hydrogen atoms or hydrocarbon radicals, e.g. methyl, ethyl, n-propyl, phenyl or benzyl radicals. The diol may be in the form of its cis-isomer, its transiso...
