    Abstract: The invention relates to a continuous method for producing polyalkylene arylates A) containing highly branched or hyperbranched polymers B) and optionally lubricants C). According to said method, an aromatic dicarboxylic acid or esters thereof or ester forming derivatives are esterified or interesterified with a molar surplus of an aliphatic dihydroxy compound and the resultant interestification or esterification product is polycondensed. The method is characterised in that component B) and optionally component C) is/are added to the polymer melt when at least 80 % of the desired viscosity number has been reached and the melt is optionally recondensed, discharged, cooled and granulated and that component B is composed of at least one highly branched or hyperbranched polycarbonate B1) with an OH number of between 1 and 600 mg KOH/g polycarbonate (conforming to DIN 53240, part 2), or at least one highly branched or hyperbranched polyester B2) of the type AxBy, where x equals at least 1.1 and y equals at least 2.1, or mixtures thereof.

    CPC classification number: C08G71/02

    Abstract: The invention relates to a method for the production of highly functional, highly branched polyureas. One or several ureas are transformed by means of one or several amines having at least two primary and/or secondary amino groups. At least one amine comprises at least three primary and/or secondary amino groups.
