ABSTRACT:
Process for the preparation of aliphatic polycarbonates by polymerizing cyclic aliphatic carbonates in the presence of initiators and/or catalysts, in which the initiators used are alkoxy silanes of the formula ##STR1## in which R.sub.1, R.sub.2 and R.sub.3 independently of one another represent a C.sub.1 -C.sub.4 -alkyl radical, n is an interger from 1 to 6 and
