Kinetics and modeling of melt polycondensation reaction for synthesis of poly(butylene succinate-co-butylene terephthalate) I. Esterification
PBST is an important biodegradable aliphatic-aromatic copolyester. Its synthesis and properties have been intensively studied, but no report deals with its polymerization kinetics and modeling up to now. As the first part of a series of studies on PBST, the kinetics of the TBT-catalyzed homogeneous SA/BDO and heterogeneous TPA/BDO esterifications were investigated experimentally and theoretically ...

Co-delivery of siRNA and Paclitaxel into Cancer Cells by Biodegradable Cationic Micelles Based on PDMAEMA-PCL-PDMAEMA Triblock Copolymers
Biodegradable cationic micelles were prepared from PDMAEMA-PCL-PDMAEMA triblock copolymers and applied for the delivery of siRNA and paclitaxel into cancer cells. PDMAEMA-PCL-PDMAEMA copolymers were readily obtained by reversible addition-fragmentation chain transfer (RAFT) polymerization of dimethylaminoethyl methacrylate (DMAEMA) using CPADN-PCL-CPADN (CPADN: 4-cyanopentanoic acid dithionaphthal...

“Alternative Block Polyurethanes Based on Poly(3-hydroxybutyrate-co-4-hydroxybutyrate) and Poly(ethylene glycol)” Biomaterials 2009, 30(16), 2975-2984.
A series of amphiphilic alternative block polyurethane copolymers based on poly(3-hydroxybutyrate-co-4-hydroxybutyrate) (P3/4HB) and poly(ethylene glycol) (PEG) were synthesized by a facile way of coupling reaction between P3/4HB-diol and PEG-diisocyanate, with different 3HB, 4HB, PEG compositions and segment lengths. Stannous octanoate was used as catalyst. The chemical structure, alter...

Effects of porosity and pore size on in vitro degradation of three-dimensional porous poly(D,L-lactide-co-glycolide) scaffolds for tissue engineering
In vitro degradation of seven three-dimensional porous scaffolds composed of PLGA85/15, a very useful poly(d,l-lactide-co-glycolide), was performed in phosphate buffered saline solution at 37°C up to 26 weeks, and effects
of porosity (80–95%) and pore size (50–450 m) on the degradation of the scaffolds were investigated. A series o...

In vitro degradation of three dimensional porous poly(D,L-lactide-co-glycolide) scaffolds for tissue engineering
In vitro degradation behaviors of three-dimensional tissue engineering porous scaffolds made from amorphous poly(d,l-lactideco-glycolide) with three different formulations have been systematically investigated up to 26 weeks in phosphate buffer saline solution at 37C. The following properties of the scaffolds were measured as a function of degradation time: dimensions,weight, compressive strength...

Surface modification of poly(styrene-b-(ethylene-co-butylene)-b-styrene) elastomer via photo-initiated graft polymerization of poly (ethylene glycol)
关键字：Poly(styrene-b-(ethylene-co-butylene)-b-styrene) (SEBS) copolymer, Photo-initiated graft polymerization, Poly(ethylene glycol) methyl ether methacrylate (PEGMA), Wettability, Hemocompatibility
Poly(styrene-b-(ethylene-co-butylene)-b-styrene) (SEBS) copolymer biomedical elastomer was covalently grafted with poly(ethylene glycol) methyl ether methacrylate (PEGMA) via a photo-initiated graft polymerization technique. The surface graft polymerization of SEBS with PEGMA was verified by ATR–FTIR and XPS. Effect of graft polymerization parameters, i.e., monomer concentration, U...
