Abstract:
A phosphite represented by the formula (I): ##STR9## wherein n represents 1 or 2; A represents an alkylene group having 1 to 8 carbon atoms;B represents a direct bond or an alkylene group having 1 to 8 carbon atoms;one of Y and Z represents a hydroxyl group, an alkoxy group having 1 to 8 carbon atoms or an aralkyloxy group having 7 to 12 carbon atoms, and the other one represents a hydrogen atom or an alkyl group having 1 to 8 carbon atoms;X represents a phosphorous-containing group represented by the formula (II): ##STR10## wherein R.sup.1 and R.sup.2 independently represent a hydrogen atom, an alkyl group having 1 to 8 carbon atoms, a cycloalkyl group having 5 to 8 carbon atoms, an alkylcycloalkyl group having 6 to 12 carbon atoms, an aralkyl group having 7 to 12 carbon atoms or a phenyl group; R.sup.3 represents a hydrogen atom or an alkyl group having 1 to 8 carbon atoms; and R.sup.4 represents a hydrogen atom, an alkyl group having 1 to 8 carbon atoms, a cycloalkyl group having 5 to 8 carbon atoms, an alkylcycloalkyl group having 6 to 12 carbon atoms, an aralkyl group having 7 to 12 carbon atoms or a phenyl group, or the two R.sup.4 may be combined with each other to form a direct bond, a sulfur bond (--S--), or a methylene group which is optionally substituted with alkyl having 1 to 8 carbon atoms or cycloalkyl having 5 to 8 carbon atoms;R.sup.5 and R.sup.6 independently represent a hydrogen atom, an alkyl group having 1 to 8 carbon atoms, a cycloalkyl group having 5 to 8 carbon atoms, an alkylcycloalkyl group having 6 to 12 carbon atoms, an aralkyl group having 7 to 12 carbon atoms or a phenyl group;R.sup.8 represents a hydrogen atom or an alkyl group having 1 to 8 carbon atoms; andR.sup.7 represents a hydrogen atom or an alkyl group having 1 to 8 carbon atoms when n is 2, or R.sup.7 represents a hydrogen atom, an alkyl group having 1 to 8 carbon atoms or a group of --CH(R.sup.8)--A--O--X (in which R.sup.8, A and X are as defined above) when n is 1.
