Zusammenfassung: | A coating or adhesive composition comprises an organic solvent solution of an isocyanatoaryl phosphorus compound of formula where X is oxygen or sulphur, n is 0, 1 or 2, A represents a radical obtained by removing two active hydrogen atoms from a di-hydroxy-terminated polyester, polyether or alcohol; R is an unsubstituted or substituted O-aryl, O-aralkyl, O-alkaryl, O-cycloalkaryl, S-aryl, S-aralkyl, S-alkaryl, S-cycloalkaryl, N-(aryl)2, N-aryl-N-alkyl, N-(aralkyl)2, N-(alkaryl)2 or N-(cycloalkaryl)2; R1 and R1 are the same or different and may be the same groups as defined for R or may be unsubstituted or substituted O-alkyl, O-cycloalkyl, S-alkyl, S-cycloalkyl, N-(alkyl)2, N-(cycloalkyl)2, N-(cyclopentadienyl)2 O-vinyl, O- or S-cyclopentadienyl or chlorine; said compound also contains at least two aromatically bound isocyanate groups; substituents in the "R" groups may be halogen, alkoxy, carboxylic ester or unsaturated hydrocarbon groups. The phosphorus compounds may be used in the form of adducts with polyhydric alcohols. Suitable solvents include aromatic hydrocarbons, chlorinated hydrocarbons, ketones and esters. The compositions may also contain natural or synthetic rubbers, e.g. 5-30% rubber and 5-50% isocyanate. The ratio of rubber to isocyanate may be from 10:1 to 1:10, preferably 3:1 to 1:3, e.g. 1:1. In Example 3, a natural rubber composition containing fillers, vulcanizers and colouring matter is dissolved in benzine and mixed with a methylene chloride solution of tri-p-isocyanatophenyl phosphate and the resulting mixture applied by dipping, brushing or spraying to rubber articles and dried at room temperature. Specification 891,654 is referred to.ALSO:A natural or synthetic rubber composition used as a coating or adhesive composition comprises an isocyanato-aryl phosphorus compound of formula where X is oxygen or sulphur, n is 0, 1 or 2, A represents a radical obtained by removing two active hydrogen atoms from a di-hydroxy-terminated polyester, polyether or alcohol; R is an unsubstituted or substituted O-aryl, O-aralkyl, O-alkaryl, O-cycloalkaryl, S-aryl, S-aralkyl, S-alkaryl, S-cycloalkaryl, N-(aryl)2, N-aryl-N-alkyl, N-(aralkyl)2, N-(alkaryl)2 or N-(cycloalkaryl)2; R1 and R1 are the same or different and may be the same groups as defined for R or may be unsubstituted or substituted O-alkyl, O-cycloalkyl, S-alkyl, S-cycloalkyl, N-(alkyl)2, N-(cycloalkyl)2, N-(cyclopentadienyl)2 O-vinyl, O- or S-c |
