    摘要： In a method for producing a homopolyester or copolyester obtainable from at least one cyclic monomer, the at least one cyclic monomer is polymerized in the presence of an initiator. The initiator is selected from organo-tin compounds, tin carboxylates, and tin alkoxides of the oxidation state II or IV that may contain optionally hydroxy groups. At the latest at a point in time when a desired degree of polymerization is reached, a phosphinic acid and/or a phosphinic derivative of the formula (R1)(R2)P(═O)X is added, wherein R1 and R2 each are independently of one another hydrogen, alkyl, aryl, or hetero aryl, and X is —OR3 or —NR1R2, wherein R3 is hydrogen, alkyl, aryl, MI or ½MII and MI is an alkali metal ion and MII is an alkaline earth metal ion and wherein the substituents R1 and R2 have the meaning indicated above.

    摘要： The invention relates to aminoplastics, which are created by reacting comnds that contain amide groups with glutaric dialdehyde, and to a process for their preparation and to their use. The aminoplastic according to the invention is free of formaldehyde and can be hardened without difficulty by acidic catalysis or thermal processes. The aminoplastic is prepared by polycondensation of compounds that contain amide groups with glutaric dialdehyde in aqueous solution.
