    Abstract: Process for the treatment of fibres e.g. of nylon or polyester/cotton in which the fibres are contacted with a polydiorganosiloxane having at least one -OM group, in which M represents H, alkyl or alkoxyalkyl, and at least one quaternary ammonium salt substituent -RN+(R")2R'X- in which R represents a divalent hydrocarbon or hydrocarbonoxy group, R' represents a monovalent hydrocarbon group or an alkyleneoxy or polyalkyleneoxy group, each R" represents methyl or ethyl and X represents a halogen atom. The treatment facilitates the removal of oily stains during laundering and may be applied in conjunction with other silicones.

    Abstract: Organosiloxane-oxyalkylene copolymers are described in which a group of the formula … … is bonded to at least one silicon atom of an organosiloxane unit, where X is a divalent hydrocarbon group, R is an alkylene group, n denotes a whole number greater than or equal to 2, Z is an epoxy group-containing organic substituent, R' denotes lower alkyl, vinyl or phenyl, R'' is alkyl or alkoxyalkyl and a denotes 0 or 1, at least 40% of all the substituents in this copolymer being methyl. These copolymers are film-forming and can be applied from aqueous or non-aqueous solutions to coherent or porous substrates.

    Abstract: Organosiloxane-oxyalkylene copolymers in which at least one silicon atom of an organosiloxane unit has attached thereto a group in which X is a divalent hydrocarbon group, R is an alkylene group, n is an integer of at least 2, Z is an organic substituent containing an epoxy group, R' is lower alkyl, vinyl or phenyl, R'' is alkyl or alkoxyalkyl and a is 0 or 1, at least 40 percent of the total substituents in the copolymer being methyl. The copolymers are film forming and may be applied to continuous or porous substrates from aqueous or non-aqueous solutions.

    Abstract: Process for the preparation of organosiloxane polymers wherein there are reacted together (A) a silanol-terminated polydiorganosiloxane in which at least 50% of the organic substituents are methyl, and (B) a quaternary ammonium silane RR'2Si-Q-N+X2YZ31 wherein R' represents an alkoxy or alkoxyalkoxy group, R represents alkyl, phenyl, vinyl or a group as defined for R', Q represents a divalent group, X represents alkyl, aryl, aralkyl or alkaryl, Y represents a monovalent hydrocarbon group or the group (-OM)aOD, wherein M represents an alkylene group having 2 or 3 carbon atoms, a has a value of from 1 to 20 and D represents H, alkyl or acyl, and Z is a halogen atom. The organosiloxane polymers can be crosslinked and are useful for the treatment of textiles.
