USE OF ORGANOMODIFIED SILOXANES FOR THE TREATMENT OF SURFACES OF THERMOPLASTIC ELASTOMERS

摘要

Use of organomodified polysiloxane (I) as additives for the improvement of the surface coating, scratching stability and the friction resistance in thermoplastic elastomers. Use of organomodified polysiloxane of formula (I) as additives for the improvement of surface coating, scratching stability and friction resistance in thermoplastic elastomers. R1aliphatic or aromatic 1-20C hydrocarbon; R2, R2a(O-alkyl)d]e-(O)k-R3; R3H, 1-20C alkyl or -(CH2-CHR4)h-(O)k-phenyl (R5)f; R4H or CH3; R51-20C alkyl (optionally branched) or -CH2-CHR4 (O)m-phenyl (R5)g; a : 0-500; b, c : 0-50; d : 0-30; e, h, k, m : 0-1; and f, g : 0-4. When (I) is greater than or equal to 5%, the Si atom of (I) is bound to the residue of R3 of formula -(CH2)2-CHR4)h-(O)k-phenyl(R5)f. [Image].
