摘要： Apparatuses and processes may be utilized for mixing used polyester into a polyester melt. In some processes an intermediate product stream is branched off from an intermediate stage in a virgin polyester production process. The intermediate product stream is then mixed with recycled polyester flakes in a dynamic mixer, where not more than 60% of a melting energy required to melt all the recycled polyester flakes is generated and/or supplied in the dynamic mixer. The mixture produced in this way is fed into a subsequent stage downstream of the intermediate stage and converted up to the desired degree of polycondensation. In this way, it is possible to physically reutilize used polyester or polyester waste.

摘要： A process for preparing a high molecular weight heteraromatic polyester or copolyester is disclosed. A process for preparing a high molecular weight heteroaromatic polyester or copolyester includes the steps of: (a) processing comonomers by mixing together to form a homogeneous solution (1) at least one heteroaromatic dicarboxylic acid having 2-12 carbon atoms or a diester or an acid anhydride derived therefrom, or a mixture thereof; (2) at least one alcohol having 2 to 12 carbon atoms and at least two hydroxyl functionalities; and (3) optionally aromatic or aliphatic dicarboxylic acids or diesters or acid anhydrides derived therefrom; (b) converting the paste/solution obtained in step a) into an esterification product containing at least one diester or at least one oligoester formed from the at least one heteroaromatic dicarboxylic acid and the at least one alcohol; and (c) polycondensing/copolycondensing the reaction product obtained from step b) under reduced pressure.

摘要： The invention relates to a method for the production of a high-molecular polyester or copolyester which comprises at least three method steps. In a first method step, a paste is produced from at least one aromatic dicarboxylic acid or the diester thereof or the acid anhydride thereof and also from at least one aliphatic dicarboxylic acid or the diester thereof or acid anhydride thereof and also from at least one dialcohol and also the required quantity of transesterification- or polycondensation catalyst. This paste is converted into a prepolymer in a second step at increased temperature and, in the third method step, this obtained prepolymer is polycondensed or copolycondensed at reduced pressure relative to normal conditions. The implementation of the method can be effected continuously and also discontinuously. Furthermore, the invention relates to polyesters and copolyesters produced in this way and also to biodegradable polymer blends comprising these. The polyesters and copolyesters according to the invention are used for the production of compostible moulded articles, biodegradable foams and paper-coating means.

摘要： The present invention relates to a method for the production of aliphatic polyesters in a two-step method. There are thereby added, in a first step, to a precondensate of an aliphatic dicarboxylic acid or to a mixture of aliphatic dicarboxylic acids and an aliphatic dialcohol or to a mixture of aliphatic dialcohols, further monomeric components, i.e. further aliphatic dicarboxylic acids and also a further aliphatic dialcohol, a polyester prepolymer being obtained. In a further step, polycondensation of the prepolymer obtained in the first step is effected.
