摘要： The invention relates to tetrahydrofuran derivatives of the formula (I) in which the radical R1 has the definition (CH2═CH—CO—O—(CHR3—CH2—O)m—CH2)— and the radical R2 has the definition (CH2═CH—CO—O—(CHR4—CH2—O)n—CH2)—, in which the radicals R3 and R4 independently of one another are hydrogen or methyl, and with the proviso that the sum of the indices m and n is a number in the range from 0 to 20.The compounds (I) are suitable for coating the surfaces of solid substrates, more particularly for coating plastics.

摘要： The present invention relates to a process for the preparation of a spinnable composition (sC) by mixing at least one terephthalate polyester (A), at least one aliphatic-aromatic polyester (B), at least one oligomer (C) and optionally at least one additive (D). Moreover, the present invention relates to the spinnable composition (sC) obtained by this process, a process for the preparation of polyester fibers (PF) by extruding the spinnable composition (sC) through at least one spinneret, the polyester fibers (PF) obtained by this process, textile materials (T) comprising the polyester fibers (PF) a process for dying the textile materials (T), and the use of the oligomer (C) for the improvement of the rheology and/or the dyeability of a composition comprising at least one terephthalate polyester (A) and at least one aliphatic aromatic polyester (B).

摘要： The present invention relates to a process for producing a surface-functionalized molding (oF) having a functionalized surface (fO). In this process a surface (O) of a molding (F) is brought into contact with a dienophile-containing solution (dL). The surface (O) comprises a polyamide (P) which comprises furan units. These furan units are able to react with the at least one dienophile present in the dienophile-containing solution (dL) to give the surface-functionalized molding (oF) having the functionalized surface (fO).
