Thermoplastische biologisch abbaubare Polysaccharidderivate, Verfahren zu ihrer Herstellung und ihre Verwendung

Thermoplastic, biodegradable polysaccharide ether esters are of formula (I): Polysaccharide-O-R (I) R = either: (i) a mono- or polymeric substd. X; or (ii) depending on the degree of substitution with X, also H and/or 1-4 (pref. 1 - 2)C alkyl; X = -A-BA'-; A, A' = linear polyether chains o...

Zusammenfassung:	Thermoplastic, biodegradable polysaccharide ether esters are of formula (I): Polysaccharide-O-R (I) R = either: (i) a mono- or polymeric substd. X; or (ii) depending on the degree of substitution with X, also H and/or 1-4 (pref. 1 - 2)C alkyl; X = -A-BA'-; A, A' = linear polyether chains of formula (-D-O)n or (-D-O)mH respectively; D = 2-11C aliphatic chain; n = 0 or an integer; m = 1 or higher; B = -C(O)-E-C(O)-O-; E = aromatic or aliphatic C framework opt. further substd.; and ratio A' : B = 0.1 or higher. Also claimed is prepn. of the thermoplastic, biodegradable polysaccharide ether ester.
