Abstract

1402182 Nitrogen - containing polyoxyalkylene - polysiloxane copolymers IMPERIAL CHEMICAL INDUSTRIES Ltd 30 March 1973 [10 April 1972] 16403/72 Addition to 1257650 Headings C3T and C3R An organopolysiloxane copolymer comprises one or more units of the general formula where R is a substituted or unsubstituted monovalent hydrocarbon group R<SP>1</SP> is a divalent organic group R<SP>2</SP> is a hydroxyalkyl or hydroxycycloalkyl group R<SP>111</SP> is a monovalent hydrocarbon group an acyl group, an N-substituted carbamyl group or a divalent group of the general formula, -CON(R<SP>2</SP>)(R<SP>1</SP>)-, the remaining valency of R<SP>1</SP> being satisfied by another Si-atom in the same or another polysiloxane block, x is 0, 1 or 2, y is 1 or 2, n is 2, 3 or 4, and z is 2-100, the remaining units, if any, being of the general formula R b SiO (4-b)/2 where R is as above defined except that a small proportion thereof may be hydrogen and b is 0-3. The copolymers may be prepared by reacting an organopolysiloxane containing one or more units of the formula R x Si(H) y O 4-x-y/2 either alone or with one or Wore units of the formula R b SiO (4-b)/2 with either an unsaturated polyoxyalkylene carbamate of the formula where R<SP>v</SP> is the ethylenically unsaturated precursor of R<SP>1</SP>, when R<SP>111</SP> is monovalent, or with a dicarbamate of the formula In Examples 1-3 a polyoxyalkylated 2- methoxyethanol of formula (Examples 1, 2) or (Example 3) is reacted with phosgene to give the chloroformate and then with N-2-hydroxypropylallylamine to give the polyether N- al y - N - 2 - hydroxypropylcarbamate, and this is reacted with a trimethylsilyl-ended dimethylsiloxane - methylhydrogensiloxane copolymer containing 28-48 Si atoms in the presence of bis-(diethyl sulphide) platinous chloride in toluene. The procedure of Example 4 is similar to that of Example 3 except that the amine used is N-(2-hydroxy-2-phenyl) ethyl allylamine. The product of Example I is used as a cell control agent and stabilizer in the manufacture of a rigid polyurethane foam by mixing an oxypropylated glycerol of M.wt. 312, 4,4<SP>1</SP>- diisocyanatodiphenylmethane, trichlorofluoromethane, tri(betachloroethyl)phosphate, Pluronic (Registered Trade Mark), N,N-dimethylcyclohexylamine, water and the polysiloxanepolyoxyalkylene copolymer of Example 1 and allowing the mixture to foam.
