Abstract

Abstract A resinous condensed cyclic alkane or alkene carboxylic WHEREIN R1, R2, R3 and R4 are each carboxyl, alkoxycarbonyl or hydrogen but one or two of R1 to R4 are always carboxyl or alkoxycarbonyl of which the alkoxy moeity has 1 to 6 carbon atoms and, when more than one carboxyl or alkoxycarbonyl is present, they can not be present at the adjacent positions; R5 is alkyl having 1 to 6 carbon atoms which may be present at any position from the 1- to 9a-positions; m and n are each an integer of 0 or 1 but at least one of them is 1; x is an integer of 0 to 3; and not more than one double bond may be present between the positions indicated by a dotted line and, when present, carboxyl or alkoxycarbonyl can not exist at such positions, which is useful for the production of an emulsifying agent effective in the emulsion polymerization for the production of synthetic rubber.
