Abstract: New oligomeric 4,4-diarylbutadiene carboxylic acid ester or amide sunscreen compounds. Oligomeric 4,4-diarylbutadiene carboxylic acid esters or amides of formula (I) are new. R1, R2 = H; aliphatic-, cycloaliphatic-, aromatic- or araliphatic- group; or carboxylate, sulfonate or ammonium; R3 = aliphatic, cycloaliphatic, aromatic, araliphatic or heterocyclic group; carbonyl, sulfonyl, phosphonyl, carboxylic acid ester or CN; Y = O or N(R4); R4 = H or aliphatic-, cycloaliphatic-, aromatic-,araliphatic or heterocyclic group; m = 2-10; n = 1-3 X = the residue of a polyol with 2-10 OH groups (corresponding to m). Am Independent claim is included for preparation of (I).
