EMPLOYMENT OF ORGANICALLY MODIFIED SILOXANES FOR THE TREATMENT OF THERMOPLASTIC ELASTOMER SURFACES.

摘要

Use of organically modified polysiloxanes of the general formula (I) where R1, independently of each other, are aliphatic or aromatic hydrocarbon residues C1-20, R2, R2 * - [(O Alk] d)] e- (O) k-R3 same or different with R3 H, optionally branched C1-20 alkyl moiety, - (CH2-CHR4) h- (O) k-Ph (R5) f, R4 H, CH3, R5 optionally branched C1-20 alkyl moiety , -CH2-CHR4- (O) m-Ph (R5) g, Alk C1-4 alkyl radical Ph phenyl radical, a 0 to 500, b 0 to 50, c 0 to 50, d 0 to 30, e 0 or 1, f 0 to 4, g 0 to 4, h 0 or 1, k, m 0 or 1, with the proviso that in at least 5% of the Si atoms of the organically modified siloxanes of the general formula I, a R3 moiety of the general formula - (CH2) 2-CHR4) h- (O) k-Ph (R5) f is attached as an additive for the improvement of surface finish, scratch resistance and abrasion resistance in thermoplastic elastomers.
