Title: Organo derivatives of polymeric oxides
Inventor: HUNTER DONALD NOEL
IPC: C08G79/04
Filed: 1960-01-04
Abstract: Organo-derivatives of polymeric oxychlorides are prepared by reacting a polymeric oxychloride having the formula: <FORM:0969196/C1/1> where M is an element of valency at least 3, x is not zero, the sum x+y equals the valency of the element and n is an integer of at least 2, with an organic reagent capable of reacting with the oxychloride to form a derivative thereof having organic radicals linked to the element M.  The element M may be aluminium, titanium, tin, phosphorus, germanium, zirconium, thorium, chromium, uranium or iron. In examples (1): <FORM:0969196/C1/2> is prepared from polydichlorostannoxane, chlorobenzene and sodium; (3): <FORM:0969196/C1/3> is prepared from polychloroaluminoxane and ethyl phosphate; (4): <FORM:0969196/C1/4> is prepared from polychloroaluminoxane and tritolyl phosphate; (7): <FORM:0969196/C1/5> is prepared from polymeric phosphorus oxychloride and butylamine; and (8): <FORM:0969196/C1/6> is prepared from polymeric phosphorus oxychloride and phenol.  The products may be used in the preparation of surface coatings and investment moulds. Specification 924,509 is referred to.ALSO:Organo-derivatives of polymeric oxychlorides are prepared by reacting a polymeric oxychloride having the formula: <FORM:0969196/C3/1> where M is an element of valency at least 3, x is not zero, the sum x+y equals the valency of the element and n is an integer of at least 2, with an organic reagent capable of reacting with the oxychloride to form a derivative of the oxychloride having organic radicals linked to the element M. The element M may be aluminium, titanium, tin, phosphorus, germanium, zirconium, thorium, chromium, uranium or iron. Organic reagents specified are Grignard Reagents, e.g. methylmagnesium chloride; organic compounds of an alkali/metal, e.g. phenyl sodium; alcohols, e.g. butyl alcohol; phenols, e.g. phenol; amines, e.g. butylamine; alkali metal salts of organometallic or organometalloid compounds, e.g, sodium salt of triphenylsilanol; and esters capable of eliminating halogen as alkyl or aryl chloride, e.g. ethyl phosphate, ethyl orthosilicate and tritolyl phosphate. In the examples (1) <FORM:0969196/C3/2> is prepared from polydichlorostannoxane, chlorobenzene and sodium; (2) <FORM:0969196/C3/3> is prepared from polydichlorotitanoxane and ethylorthosilicate; (3) <FORM:0969196/C3/4> is prepared from polychloroaluminoxane and ethyl phosphate; (4) <FORM:0969196/C3/5> is prepared from polychloroaluminoxane and tritolyl phosphate; (5) <FORM:0969196/C3/6> is prepared from polydichlorotitanoxane and the sodium salt of triphenyl silanol; (6) <FORM:0969196/C3/7> is prepared from polydichlorotitanoxane and butyl alcohol; (7) <FORM:0969196/C3/8> is prepared from polymeric phosphorus oxychloride and butylamine; and (8) <FORM:0969196/C3/9> is prepared from polymeric phosphorus oxychloride and phenol.  The organoaluminium and organotitanium polymers may be used in high temperature stable surface-coating compositions; e.g. the ethylsilicate substituted polytitanoxane may be blended with fillers and pigments and cross-linked by atmospheric moisture. Products useful in the preparation of investment moulds for precision casting may also be prepared.  The Provisional Specification also specifies M. as being silicon and describes the preparation of polydimethylsiloxane from polydichlorsiloxane and methylmagnesium chloride and polybenzylchlorosiloxane from polydichlorosiloxane and toluene. Specification 924,509 is referred to.
