Aliphatic polyester-based biodegradable materials: new amphiphilic graft copolymers

Physical properties and biodegradability of maleated-polycaprolactone/starch composite

“…2(B)]. For unmodified PCL, we found that the hydrogen peaks only appeared at five values (1: =4.01 ppm; 2: =1.48 ppm; 3: =1.25 ppm; 4: =1.56 ppm; 5: =2.15 ppm), a similar outcome to other works [23,24]. The spectrum of PCL-g-MAH showed a sixth peak at =1.8-2.0 ppm and a seventh at =2.2-2.4 ppm.…”

In situ photopolymerization of PEGDA‐protein hydrogels on nanotube surfaces

“…Similar trends in enthalpy associated with crystallization have been observed for poly(e-caprolactone-polysaccharide blends). 98,99 The decrease in enthalpy in the presence of BSA bound nanotubes is mostly likely because of high degree of hydrogen bonding interactions as well as hydrophobic interactions between the components of the hydrogels and the inability to form a highly crystalline structure. Thus, the incorporation of BSA into the nanotubes before the photopolymerization of PEGDA modifies the crystalline structure as well as the hydrophilicity of the nanotube hydrogels.…”

Nanoparticles prepared by blending of carboxylic acid terminated poly(ε‐caprolactone) and L‐phenylalanine substituted dextran

“…Thus, they are commonly prepared from biodegradable polymer such as polysaccharides and biocompatible polyesters by self-assembling of polysaccharidepolyester copolymers. [6][7][8] Methods for preparing polysaccharide-polyester copolymer include a catalytic ring-opening polymerization of monomers (lactide or caprolactone) in the presence of polysaccharides [9][10][11] and bulk polymerization of monomers in the presence of partially protected hydroxyl groups of polysaccharides, [12][13][14] followed by deprotection. The first approach is the difficulty to obtain controlled structures because all the hydroxyl groups on the polysaccharides, except the ones sterically hindered, initiate the polymerization.…”
