FUNCTIONALIZED POLYOXYMETHYLENE BLOCK COPOLYMERS |
摘要 |
The invention relates to a method for producing functionalized polyoxymethylene block copolymers comprising the step of polymerizing formaldehyde in a reaction vessel in the presence of a catalyst, the polymerization of formaldehyde in addition taking place in the presence of a starter compound comprising at least 2 Zerewitinoff active H atoms, to obtain an intermediate product. The intermediate product obtained is subsequently reacted with a cyclic carboxylic acid ester or carbonic acid ester, thus obtaining a functionalized polyoxymethylene block copolymer. The invention further relates to functionalized polyoxymethylene block copolymers obtained by such a method and to the use of said copolymers. |
