  • Patent number: 9790328
    Abstract: 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 relates to polyethercarbonate-polyoxymethylene block copolymers that can be obtained by means of such a method and to the use of same to produce polyurethane polymers.

  • Patent number: 9469715
    Abstract: The invention relates to a method for producing non-alternating formaldehyde/CO2 copolymers, said method comprising the step of reacting formaldehyde or a compound that releases formaldehyde with carbon dioxide in the presence of a catalyst system. Said method is characterized in that the catalyst system comprises a Lewis acid component and a basic component, the Lewis acid component being at least temporarily coordinatively unsaturated under reaction conditions and the basic component having a pKb value of >=0.
