“…A large number of applications of PVA and its derivatives can be found in several fields, in particular for the development of biomedical, cosmetic, textiles, paper, and adhesives. [46][47][48][49] Several other aldehydes have been grafted on PVA [49][50][51][52][53][54][55][56][57][58][59][60][61][62][63][64][65] and poly(vinyl acetals) have been utilized, among others, to obtain Langmuir-Boldgett films, 50,51 membranes for ultrafiltration, 66 fluorescent polymers for biomedical uses, 67 or anti-corrosions agents for material science. [29][30][31][32][33][34][35][36][37][38][39][40][41][42][43][44] Thus, PVA acetalization with aldehydes has also been reported 45 and some of the resulting poly(vinyl acetals) are commercially available.…”
