Procedure

The particularly preferred PTHF acetate or THF copolymer acetates may be worked up by methods known per se. For example, after distillative removal of unconverted THF and then acetic anhydride, acetic acid and comonomer, the PTHF acetate or THF copolymer acetate obtained may be transesterified using methanol under base catalysis to give PTHF or THF copolymer and methylacetate.
