Procedure

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