Compatibilization of polyamide 6/poly(2,6-dimethyl-1,4-phenylene oxide) blends by poly(styrene-co-maleic anhydride)
The properties of polyamide 6 (PA6)/poly(2,6-dimethyl-1,4-phenylene oxide) (PPO) blends compatibilized by poly(styrene-co-maleic anhydride) (SMA) were studied. The addition of SMA can form an in situ copolymer, SMA-graft-PA6. The SMA-graft-PA6 copolymer actually plays a key role as a compatibilizer to improve the interface between PA6 and PPO. It was found that the effect of compatibilization resu...

Influence of poly(butylenes adipate-co-terephthalate) on the properties of the biodegradable composites based on ramie/poly(lactic acid)
Ramie/poly(lactic
acid) (PLA) composites were prepared by using two-roll mill. Poly(butylenes adipate-co-terephthalate)
was added into the composites, and the effect of PBAT on the mechanical
properties and thermal properties of the composites was investigate. The tensile
and flexural strength decreased with the increase of PBAT content, and the
addition of a small amount of PBAT increased the imp...

Preparation and characterization of biodegradable poly(lactic acid)-block-poly(ε-caprolactone) multiblock copolymer
Biodegradable copolymers of poly(lactic acid)-block-poly(e-caprolactone) (PLA-b-PCL) were successfully prepared by two steps. In the first step, lactic acid monomer is oligomerized to low molecular weight prepolymer and copolymerized with the (e-caprolactone) diol to prepolymer, and then the molecular weight is raised by joining
prepolymer chains together using 1,6-hexamethylene diisocyanate (HDI)...

In vivo degradation behavior of porous composite scaffolds of poly(lactide-co-glycolide) and nano-hydroxyapatite surface grafted with poly(L-lactide)
Intramuscular implantation test of 20w showed that porous composite scaffolds of surface grafted g-HAP/PLGA and ungrafted n-HAP/PLGA presented slower degradation and higher mineralization compared to that of pure PLGA. Compared with n-HAP/PLGA, g-HAP/PLGA showed an improved absorption and biomineralization because of its improved distribution of g-HAP nanoparticles in PLGA matrix. &nb...

In vivo mineralization and osteogenesis of nanocomposite scaffold of poly(lactide-co-glycolide) and hydroxyapatite surface-grafted with poly(l-lactide). Biomaterials, 2009,30: 58–70
[Abstract]: Nanocomposite of hydroxyapatite (HAP) surface-grafted with poly(l-lactide) (PLLA) (g-HAP) shows a wide application for bone fixation materials due to its improved interface compatibility, mechanical property and biocompatibility in our previous study. In this paper, a 3-D porous scaffold of g-HAP/poly(lactide-co-glycolide) (PLGA) was fabricated using the solvent casting/particu...

A branching point thermo and pH dual-responsive hyperbranched polymer based on poly(N-vinylcaprolactam) and poly(N,N-diethyl aminoethyl methacrylate)
We report the design and synthesis of a branching point stimuli-responsive hyperbranched polymer based on poly(N-vinylcaprolactam) and poly(N,N-diethylaminoethyl methacrylate) through combined“A2+BxC” (x > 2) double monomer polymerization and parallel click reaction. The results of ultraviolet-visible
spectrophotometry and dynamic light scattering (DLS) indicated that the resultant ...

Interchain Hydrogen-Bonding-Induced Association of Poly(acrylic acid)- graft-poly(ethylene oxide) in Water
Poly(acrylic acid)-graft-poly(ethylene oxide) (PAA-g-PEO) in aqueous solutions shows one fast and one slow relaxation mode in dynamic light scattering (DLS), but the mixture ofPAAandPEO(PAA/PEO) in aqueous solution only has a single fast mode. The effects of pH, polymer concentration, and salt concentration on these two modes have been investigated using laser light scattering (LLS), v...
