Novel anti-atherosclerosis agents having the formula, ##STR1## wherein R is hydrogen or lower alkyl, n and m each signify an integer of 4 - 6, and A is hydrogen or a group of the formula, ##STR2## WHEREIN R and m have the same meanings as defined above. These compounds are produced, for example, by reacting a bisphenolic compound of the formula, ##STR3## with chloroform and a ketone compound of the formula, ##STR4## in the presence of an alkali. Alternatively, they are produced by reacting the bisphenolic compound with .alpha.-halogeno- or .alpha.-hydroxycarboxylic acid derivative of the formula, ##STR5## wherein R and m have the same meanings as defined above, and X is halogen or hydroxyl.
