Polymere charge‐transfer‐komplexe auf der basis von polyvinylalkoholacetalen, 4

Abstract: Partially acetalisized poly(viny1 alcoho1)s with degrees of acetalization between 39 and 60% were prepared by reaction of poly(viny1 alcohol) with 9-isobutyl-3-carbazolealdehyde (5 a) or 3-formyl-9-((S)-2-methylbutyl)carbazole (5b). Complex formation constants and &-values of the charge-transfer complexes with ethylenetetracarbonitrile, 2,5-cyclohexadien-1 ,Cdiylidenedimalonodinitrile, 2,4,5,7-tetranitro-9-fluorenone, and 2,4,7-trinitro-9-fluorenone were determined. Circular dicroism measurements of the optica… Show more

“…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.…”

“…1 Poly(vinyl butyral) is used in particular for its coating and adhesive properties. [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. 68 Concerning the cosmetic field, only few applications of poly(vinyl acetals) have been reported and concern the formation of cosmetic sponges 69,70 and their use in masks 71 or in nail polishing, by improving their resistance and their thermal stability.…”
