    摘要: The present invention relates to a process for the preparation of carbonic acid esters of polyester-polyols by transesterifying the polyols with carbonic acid aryl esters at elevated temperatures under vacuum in the presence of a catalyst. The reaction conditions are controlled to avoid the formation of by-products and the chain extension of the polyester-polyols. The present invention is also concerned with the polyester carbonic acid esters so formed, their use in producing polycarbonate block copolymers and the copolymers so produced. The copolymers may be produced by transesterifying the polyester carbonic acid esters with bisphenols and subjecting the bis-hydroxyaryl carbonates so formed to normal polycarbonate synthesis such as interfacial or melt polycondensation.

    摘要: Homo- and copolymers of monomers obtained by acylation of 2-[4-hydroxy(or amino)phenyl]-2-[5-(8-hydroxyquinolyl)]-propane with .alpha.,.beta.-monoolefinically unsaturated carboxylic acid halides or - anhydrides. As comonomers can be employed compounds containing one or more .alpha.,.beta.-olefinically unsaturated groups such as olefines, diolefines, acrylic acid derivatives, vinyl monomers. The polymers having molecular weights between 5000 - 500,000 can be prepared by radical or ionic chain mechanisms, in continuous or discontinuous processes. They may be used for removing metal ions from their solution, for complexing of interfering metallic impurities in thermoplastic or thermosetting resins or in form of their metal complexes as stabilizers for plastics.

    摘要: Disclosed are oligomeric phosphonates including oligophosphonates, random or block co-oligo(phosphonate ester)s and co-oligo(phosphonate carbonate)s produced using a condensation process terminated with hydroxyl, epoxy, vinyl, vinyl ester, isopropenyl, isocyanate groups, and the like. These materials can be used as a reactive additive to other polymers, oligomers or monomer mixtures to impart flame resistance without diminishing melt processability which is important in the fabrication of polymers for many applications.
