Crystallization behavior and hydrophobic properties of biodegradable ethyl cellulose-g-poly(3-hydroxybutyrate-co-3-hydroxyvalerate): The influence of the side-chain length and grafting density
The copolymerization of grafting poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) onto ethyl cellulose (EC) was carried out through the homogeneous acylation reaction between EC as a backbone and telechelic OH-terminated PHBV oligomer as side chains in 1,2-dichloroethane by using 1,6-hexamethylene diisocyanate (HDI) as a coupling agent and dibutyltin dilaurate as catalyst. The resulting copol...

151. The preparation of graphene hybrid films decorated with poly[2-methoxy-5-(2'-ethyl-hexyloxy)-1,4-phenylene vinylene] particles prepared by non-solvent induced precipitation.
A hybrid film of graphene decorated with poly[2-methoxy-5-(2'-ethyl-hexyloxy)-1,4-phenylene vinylene] (MEH-PPV) nanoparticles is fabricated by a simple non-solvent induced precipitation method. The structure of the graphene film and graphene/MEH-PPV hybrid film are investigated by scanning electron microscopy, atomic force microscopy and X-ray photoelectron spectroscopy. The large specific surface...

Synthesis, Characterization and in Vitro Degradation of Ethyl Cellulose-graft-Poly (ε-caprolactone)-Block-Poly (L-Lactide) Copolymers by Sequential Ring-Opening Polymerization
Well-defined ethyl cellulose-graft-poly(-caprolactone) (EC-g-PCL) graft copolymers were successfully synthesized via ring-opening polymerization (ROP) of -caprolactone (CL) with an ethyl cellulose (EC) initiator and a tin 2-ethylhexanoate (Sn(Oct)2) catalyst in xylene at 120 °C. Then, novel ethyl cellulose-graft-poly(-caprolactone)- block-poly(L-lactide) (EC-g-PCL-b-PLLA) graft-block copoly...

Synthesis and properties of Polycaprolactone-graft-Poly(2-(dimethylamino)ethyl methacrylate-co-methoxy polyethylene glycol monomethacrylate) as non-viral gene vector
Polycaprolactone-graft-Poly(2-(dimethylamino)ethyl methacrylate-co-methoxy polyethylene glycol monomethacrylate)
(PCL-graft-P(DMAEMA-co-mPEGMMA)) was synthesized by combination of ring-opening polymerization (ROP)
and atom transfer radical polymerization (ATRP). PCL-graft-P(DMAEMA-co-mPEGMMA) was characterized by FTIR, 1H
NMR, and GPC. PCL-graft-P(DMAEMA-co-mPEGMMA) with expected composition an...
