(A) Zinc polycarboxylate cement; (B) Type I; (C) Type II; (D) Type III. For all cements tested, IR spectra of polymeric acids (modified polyacrylic acid, modified polyalkenoic acid, 35% w/w aqueous solution of PMVE-Ma (a) showed the absorption bands of carboxylic group (C=O) between 1635 to 1640 cm−1 cm (arrows). IR spectra of set cements (b) showed the absorption bands between 1558 and 1401 cm−1 indicating the formation of carboxylic salts (arrows).
