Abstract

Organosilicon cpds. of formula R1 is an opt. alkylated phenyl gp. and/or a gp. -(CH(CH3)CH2-O-)b(CH2CH2O-)cR3 where R3 is 1-16 alkyl gp., 1-12 C acyl gp. or aryl gp., opt. carrying a hydrocarbon substit. b = 0-1, pref. O; and c = 1-30, and/or a trimethylsilyl gp.; R2 is an opt. substd. 1-16C alkyl gp. in which the carbon chain may be interrupted by a -O-CO- or -CO-O- gp. and/or the residue Ma-O-R1 and/or a gp. -CH(CH3)-C6H5, R2 pref. being CH3; R4 is a 1-16C alkyl gp. and/or a gp. -O-Si(CH3)R-Ma-OR1, R4 pref. being CH3; M is an opt. substd. divalent hydrocarbon gp.; n = 2.5-20; m = 0-5 a = 0 or 1. The average mol. contains 5-40 Si atoms, of which a maximum of 20 mole % are atoms Si, and 0.2-5 opt. alkylated phenyl gps. bound directly to Si via Ma-O- bonds, and 0.2-5 polyether blocks. (I) are useful adjuvants in the prodn. of extrusion spun fibres, esp. polyester fibres. They have good heat stability and antistatic properties, and give fibres with excellent processing properties.
