Effects of Polymer-Grafted Natural Nanocrystal on Structure and Mechanical Properties of Poly(lactic acid): A Case of Cellulose Whisker-graft-Polycaprolactone
In this work, polysaccharide nanocrystals—rodlike cellulose whiskers (CWs)—were surface-grafted with polycaprolactone (PCL) via microwave-assisted ring-opening polymerization, and filaceous cellulose whisker-graft-polycaprolactone (CW-g-PCL) nanoparticles were produced. Moreover, the resultant nanoparticles were incorporated into poly(lactic acid) (PLA) as a matrix, an...

【Polym Chem】Synthesis of amphiphilic poly(cyclooctene)-graft-poly(ethylene glycol) copolymers via ROMP and its surface properties
Macromonomer cyclooctene-poly(ethylene glycol) (cyclooctene-PEG) was first synthesized before being copolymerized with cyclooctene by ring opening metathesis polymerization (ROMP) to obtain an amphiphilic graft copolymer (poly(cyclooctene)-g-PEG) with polycyclooctene as the hydrophobic trunk chain and PEG as hydrophilic side chains. The structure of poly(cyclooctene)-g-PEG copolymer was characteri...

【React Funct Polym】Synthesis of amphiphilic polycyclooctene-graft-poly(ethylene glycol) copolymers by ring-opening metathesis polymerization
In this paper, a novel monomer of 4-methyl-3-(carbamate)–carbanilic acid-4-cyclooctene ester (MCCCE) was synthesized and characterized by FTIR, NMR and ESI-MS. Polycyclooctene-graft-blocked isocyanate copolymers were prepared by the copolymerization of MCCCE and cyclooctene via ring-opening metathesis polymerization (ROMP). Amphiphilic polycyclooctene-graft–PEG copolymers were prepared by melt m...

A facile approach to modify polypropylene flakes combining O2-plasma treatment and graft polymerization of l-lactic acid
Modification of polypropylene (PP) surface with poly(l-lactic acid) (PLLA) via a facile approach was described. The PP flakes were first treated with O2 plasma and then grafted with l-lactic acid (LLA) monomer in the aqueous solution. The attenuated total reflectance Fourier transform infrared (ATRFTIR) spectroscopy, atomic force microscopy (AFM) and X-ray photoelectron spectroscopy...

A Monte Carlo study on LCCC characterization of graft copolymers at the critical condition of side chains
Liquid chromatography at the critical condition (LCCC) has been used to characterize graft copolymers based on the assumption that one of the copolymer blocks becomes chromatographically “invisible” at the critical condition of the corresponding homopolymer. We investigate the validity of this assumption with lattice Monte Carlo simulations of A-g-B graft copolymers modeled as either random walk...

Shape-stabilized phase change materials based on poly(ethelyene-graft-maleic anhydrids)-g-alkyl alcohol comb-like polymers
In this study, a series of shape-stabilized comb-like polymeric phase change materials (CLPPCMs), denoted as EMA-g-CnH2n+1OH (poly(ethylene-graft-maleic anhydride)-g-alkyl alcohol) with n=14, 16, 18, 26, were prepared through an esterification reaction between poly(ethylene-graft-maleic anhydride) (EMA) and n-alkyl alcohols (CnH2n+1OH). The structure, thermal properties and shape-stabili...

(Macromolecules) Amphiphilic Poly(Ethylene Oxide)-block-Poly(Butadiene-graft-Liquid Crystal) Copolymers: Synthesis and Self-Assembly in Water
What could be the self-assembly behaviour in aqueous
solution for an amphiphilic block copolymer with a very flexible hydrophobic
backbone possessing however a liquid crystalline (LC) order? To answer this
question, five amphiphilic block copolymers were prepared by grafting, via a
thiol-ene addition reaction, four different thiol functionnalized LC mesogens
or LC-like side groups on two commerc...

Multi-responsive graft copolymer micelles comprising acetal and disulfide linkages for stimuli-triggered drug delivery
Thermo-, pH and reduction triggered drug
delivery vehicles based on dual-cleavable polymeric micelles were investigated.
A comblike copolymer (G3) comprising one disulfide linkage and PEG, PCL and
acetal-bridged PCL-b-PNIPAM grafts was controllably synthesized by successive
RAFT copolymerization, ring-opening polymerization and adductive reaction. G3
was liable to self-assemble into spherical mice...

Radical Graft Polymerization of an Allyl Monomer onto Hydrophilic Polymers and Their Antibacterial Nanofibrous Membranes
Hydrophilic poly (vinyl alcohol-co-ethylene) (PVA-co-PE) copolymers
with 27 mol %, 32 mol % and 44 mol % ethylene were functionalized by
melt radical graft copolymerization with 2,4-diamino-6-diallylamino-1,3,5-triazine
(NDAM) using reactive extrusion. This functionalization imparts antibacterial
properties. The covalent attachments of the NDAMas side chains onto
the PVA-co-PE polymer backbones we...
