摘 要：
The present invention relates to a method for producing polyethercarbonate-polyoxymethylene block copolymers, comprising the step of polymerizing formaldehyde, wherein formaldehyde is polymerized in the presence of a
polyethercarbonate having at least one Zerewitinoff-active H atom, obtaining an intermediate product. The obtained intermediate product can be further
reacted with a cyclic carboxylic acid ester or carbonic acid ester, a cyclic anhydride, an epoxide, and/or an isocyanate,
wherein a hydroxyl- or carboxy-functional or NCO-modified polyethercarbonate-polyoxymethylene block copolymer is obtained. The present invention further
