    摘要： Thermoplastic, branched aromatic polyphosphonates with average molecular weights (number average M.sub.n) of from 11,000 to more than 200,000, obtainable by transesterifying (a) from 97 to 100 moles of at least one diaryl phosphonate, and (b) from 0 to 3 moles of at least one triaryl phosphate--the sum of the moled of (a) and (b) being 100--with (c) from 90 to 99 moles of at least one aromatic dihydroxy compound, and (d) from 0 to 3 moles of at least one aromatic trihydroxy or tetrahydroxy compound--with the proviso that at least one of the components (b) and (d) is present in a quantity of at least 0.001 mole and that, where (b) and (d) are used, the maximum limit on the moles is 3.0.

    摘要： A process for the production of an alkoxy phospholane oxide or sulphide of the formula ##STR1## in which R.sup.1 is an alkyl, alkoxy or aryl radical having up to 14 carbon atoms.R.sup.2, r.sup.3 and R.sup.4 each independently is a C.sub.1 to C.sub.4 alkyl radical, hydrogen, chlorine or bromine,R.sup.5 is an alkyl, alkenyl, alkynyl radical having from 1 to 14 carbon atoms, andX is oxygen or sulphur,Comprising reacting a phospholene oxide or sulphide of the formula ##STR2## with an alcohol of the formulaR.sup.5 -- O -- Hin the presence of an alkaline catalyst, such as sodium methylate. The products catalyze the conversion of isocyanates into carbodiimides with evolution of carbon dioxide.
