Synthesis and nuclear magnetic resonance analysis of starch‐g‐poly(1,4‐dioxan‐2‐one) copolymers

Abstract

A new biodegradable starch graft copolymer, starch‐g‐poly(1,4‐dioxan‐2‐one), was synthesized through the ring‐opening graft polymerization of 1,4‐dioxan‐2‐one onto a starch backbone. The grafting reactions were conducted with various 1,4‐dioxan‐2‐one/starch feed ratios to obtain starch‐g‐poly(1,4‐dioxan‐2‐one) copolymers with various poly(1,4‐dioxan‐2‐one) graft structures. The microstructure of starch‐g‐poly(1,4‐dioxan‐2‐one) was characterized in detail with one‐ and two‐dimensional NMR spectroscopy. The effect of the feed composition on the resulting microstructure of starch‐g‐poly(1,4‐dioxan‐2‐one) was investigated. © 2004 Wiley Periodicals, Inc.

Preparation and properties of a novel biodegradable ethyl cellulose grafting copolymer with poly(p-dioxanone) side-chains

“…Graft copolymerization can provide an efficacious method not only for providing functionality to the resulting polymers, but for regulating polymer properties. Because the ROP of lactone may be initialized easily by the hydroxyl group when Sn(Oct) 2 was used, many researchers have utilized this method to prepare graft copolymers based on PPDO and other hydrophilic polymers (Chen, Zhou, Wang, Wang, & Yang, 2006;Liu et al, 2008;Wang, Yang, Wang, Zhou, & Jin, 2004).…”

In vitro degradation of biodegradable blending materials based on poly(p‐dioxanone) and poly(vinyl alcohol)‐graft‐poly(p‐dioxanone) with high molecular weights

“…In this area, hydrophilic polymers with hydroxyl group in repeating unit have been studied intensively. Because the ring-opening polymerization of lactone or lactide may be initialized easily by the hydroxyl group when the catalyst was used, many researchers have utilized this method to prepare polyester grafted polysaccharides, for example, starch, [13][14][15][16][17][18] pullulan, 19,20 dextran, [21][22][23][24][25][26] and chitosan. [27][28][29] Poly (vinyl alcohol) (PVA) could also be esterified by the same reaction both in bulk 30 and in solution.…”

Graft polymerization of p-dioxanone onto polyhydroxyethylaspartamide through ring-opening polymerization using organometallic and enzyme catalysts

“…Graft copolymerization [13][14][15][16][17][18][19] is a versatile method to modify the PPDO for providing functionality to the resulting polymers, and for regulating polymer properties. However, there are few reports about graft copolymerization of PPDO with other polymers [20][21][22].…”
