Improvement of microstructures and properties of biodegradable PLLA and PCL blends compatibilized with a triblock copolymer

Semi-interpenetrating polymer networks composed of poly(l-lactide) and diisocyanate-bridged 4-arm star-shaped ɛ-caprolactone oligomers

“…50 MPa). Furthermore, PCL displays a better permeability and slower rate of enzymatic hydrolysis than PLA does [6][7][8]. To improve the complementary physicochemical properties of PLA and PCL, polymer blend is one of the most practical strategies [9][10][11][12][13].…”

Structure, properties and interfacial interactions in poly(lactic acid)/polyurethane blends prepared by reactive processing

“…In order to improve compatibility and achieve a more advantageous combination of properties, several methods have been applied, e.g. the addition of block copolymers such as PCL-PLA diblock [33][34][35], triblock [33,36,37] and random copolymers, a PCL-PEG copolymer [38], a PEO-PPO-PEO triblock copolymer [39] or several commercial impact modifiers [40] compatibilizers [41][42][43]. The method possesses considerable potential, since structure and properties can be controlled relatively easily by the proper selection of components, blend composition and processing conditions.…”

Estimation of the Compatibility of Blend Composites of Resins by Measuring the Fluorescent Spectra

“…[5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21] Our group developed additives for PLA, such as a nucleating agent, 22 and a layered silicate for improving the impact strength. 23 On the other hand, to make PLA with a fluorescence function, we added polymers containing diphenylamine with a bridged structure, whose bridge units were monosilane (phenazasiline: PPhenaz, Fig.…”
