    摘要: Thioaminophosphazenes containing at least one group of the formula: ##STR1## in which R is H, optionally substituted monovalent hydrocarbyl or optionally substituted divalent hydrocarbyl joining together two nitrogen atoms,R.sup.2 is optionally substituted hydrocarbyl, and represented by the formula: ##STR2## WHEREIN N = 1 TO 100, Y.sup.1 and Y.sup.2 together represent O or S, or each independently represents a monovalent substituent selected from Cl, Br, optionally substituted hydrocarbyl, optionally substituted hydrocarbyloxy and ##STR3## where R has the above meaning and R.sup.1 is H, optionally substituted hydrocarbyl or --SR.sup.2, A is a monovalent substituent of the class defined for Y.sup.1, B is H, R.sup.2, SR.sup.2, COR.sup.2 or SO.sub.2 R.sup.2, or if n is 3 or more, A and B together may represent a direct link between --P=N-- units in a cyclic structure.The products are useful in preventing premature vulcanization in vulcanizable rubber compositions.
