Abstract: Light-stabilized synthetic linear, fiber- and film-forming polyesters are obtained by incorporating into the macromolecules composed of dicarboxylic acid and diol moieties about 0.1 to 5 mole percent of structural units of the formula

IN WHICH X stands for the group

WHEREIN R1, R2 and R3 each are hydrogen or an alkyl radical having from 1 to 4 carbon atoms.

Abstract translation: 通过掺入由二羧酸和二醇部分组成的大分子中获得轻稳定的合成线性，纤维和成膜聚酯，其中约0.1至5摩尔％的式IN结构单元，其中X代表WHEREIN R1，R2 和R 3各自为氢或具有1至4个碳原子的烷基。

Abstract: NOVEL FILM AND FIBER-FORMING MODIFIED POLYAMIDES WITH AN INCREASED CONTENT OF AMINO GROUPS ARE OBTAINED, IF IN THE PREPARATION OF POLYAMIDES FROM THE COMMON STARTING COMPOUNDS, POLYAMINES ARE ADDED WHICH HAVE PARTLY AROMATIC, AND PARTLY CYCLO-ALIPHATIC MOLECULAR STRUCTURAL UNITS, OPTIONALLY IN ADMIXTURE WITH CYCLO-ALIPHATIC POLYAMINES WHICH MAY ALSO HAVE 1 ALIPHATIC C-ATOM BETWEEN THE CYCLO-ALIPHATIC RINGS AND THE AMINO GROUPS.

Abstract: POLYAMIDES HAVING AN ESPECIALLY HIGH DYE AFFINITY WITH RESPECT TO BASIC DYESTUFFS ARE OBTAINED BY ADDING CERTAIN AMOUNTS OF A POLYAMINE.

H2N-1,4-CYCLOHEXYLENE-C(-R'')(-R")-1,4-CYCLOHEXYLENE-NH-

(1,4-CYCLOHEXYLENE-C(-R'')(-R")-1,4-CYCLOHEXYLENE-NH)X-

1,4-CYCLOHEXYLENE-C(-R'')(-R")-1,4-CYCLOHEXYLENE-NH2 (I) OR

H2N-CH2-CYCLOHEXYLENE-CH2-NH-(CH2-CYCLOHEXYLENE-CH2-NH)X-

CH2-CYCLOHEXYLENE-CH2-NH2 (II)

OR A MIXTURE OF THESE POLYAMINES, IN WHICH FORMULAE X REPRESENTS ZERO OR A WHOLE NUMBER FROM 1 TO 30, PREFERABLY ZERO OR A WHOLE NUMBER FROM 1 TO 10, R2 REPRESENTS H, -CH3, -C2H5, R" REPRESENTS H8 -CH3, C2H5, AND THE BONDS OF THE RINGS IN FORMULA II PREFERABLY BEING META- AND PARA-BONDS, TO THE POLYAMIDE-FORMING STARTING MATERIAL OR SUBSEQUENTLY TO THE POLYAMIDE. FROM THE MODIFIED POLYAMIDES FIBERS ARE OBTAINED WHICH HAVE AN IMPROVED DYE AFFINITY WITH RESPECT TO BASIC DYESTUFFS.
