Lubricating agents for the production of carbon yarns

Lubricating agents for the production of carbon yarns comprise at least one organo polysiloxane of the general formula I wherein R , R , R , R and R each represent a methyl group or ethyl group; R represents a hydrogen atom, or an alkyl group with 1 to 5 carbon atoms or a -a phenyl group; R and R ea...

Beschreibung
Zusammenfassung:	Lubricating agents for the production of carbon yarns comprise at least one organo polysiloxane of the general formula I wherein R , R , R , R and R each represent a methyl group or ethyl group; R represents a hydrogen atom, or an alkyl group with 1 to 5 carbon atoms or a -a phenyl group; R and R each represents a methyl group, ethyl group or hydroxyl group, and m and n are integers such that the viscosity of the organo polysilosane at 25 DEG C is in the range of 5 to 1000 centistokes, together with at least one amino-modified polysiloxane. The amino-modified polysiloxane is preferably of the general formula (II) where R represents a hydrogen atom, or an alkyl group with 1 to 5 carbon atoms or phenyl group; R , R , R and R each represent a methyl group or an ethyl group; R and R each represent a methyl group, an ethyl group or a hydroxyl group; R , R and R each represent a hydrogen atom, (a methyl group or an ethyl group; X represents an alkylene group with 3 to 5 carbon atom; Y represents an alkylene group with 2 to 6 carbon atoms; and p and q are integers such that the viscosity at 25 DEG C of the amino-modified polysiloxane is in the range of 10 to 10000 centistokes.
