Neutron reflectivity measurements were performed on a cell membrane mimic system consisting of a polyelectrolyte multilayer plus a synthetic terpolymer plus a phospholipid layer, at all of the intermediate steps in the assembly of the composite, to obtain neutron scattering length density depth profiles. The polyelectrolyte multilayer functions as a soft, water-containing cushion for the membra...

Sharply thermo- and pH-responsive pentablock terpolymer with a core-shell-corona structure was prepared by RAFT polymerization of N-isopropylacrylamide and methacrylic acid monomers using PEG-based benzoate-type of RAFT agent. The PEG-based RAFT agent could be easily synthesized by dihydroxyl-capped PEG with 4-cyano-4-(thiobenzoyl) sulfanylpentanoic acids, using esterification reaction. This pe...

The production of the terpolymer poly(3-hydroxybutyrate-co-3-hydroxyvalerate-co-4-hydroxybutyrate), P(3HB-co-3HV-co-4HB), by Alcaligenes sp. A-04 was investigated to determine the superior biodegradable polymer properties over those of poly(3-hydroxybutyrate), P(3HB), and its copolymers. The highest terpolymer content of 68% (w/w) was produced by Alcaligenes sp. A-04 at 60 h by shake-flask cult...

A novel photocrosslinkable and melt processible terpolymer precursor for carbon fiber has been successfully synthesized and characterized. The terpolymer was synthesized by an efficient emulsion polymerization route and has a typical composition of acrylonitrile/methyl acrylate/acryloyl benzophenone in the mole ratio, 85/14/1. It has been characterized by FTIR, NMR, intrinsic viscosity and GPC ...

A regioregular terpolymer that combines electron-deficient diketopyrrolopyrrole and benzothiadiazole units with an electron-rich dithienopyrrole unit is presented. In solar cells, the terpolymer affords an open circuit voltage of 0.52 V and a power conversion efficiency of 3.7% with a spectral response up to 1050 nm.

Lactide-based polymers have been widely investigated as materials for tissue engineering. However, characteristics such as low flexibility and elongation tend to limit particular applications, although these can be enhanced by adding plasticizers such as trimethylene carbonate (TMC) to the polymer chain of the copolymer poly(L-lactide-co-D,L-lactide) (PLDLA). The aim of this work was to synthes...

We report structural, caloric, and dielectric properties of polymer blends of poly(vinylidenefluoride–trifluoroethylene–chlorofluoroethylene) terpolymer (a member of the relaxor polymers family that exhibits fast response speeds, giant electrostriction, high electric energy density, and large electrocaloric effect) and poly(vinylidenefluoride–chlorotrifluoroethylene) copolymer, developed on alu...

Terpolymer of 2-amino-6-nitro-benzothiazole-ethylenediamine-formaldehyde (BEF) has been synthesized and characterized by elemental analysis and various spectral techniques like FTIR, UV-Visible, and (1)H and (13)C-NMR. The terpolymer metal complexes were prepared with Cu(2+), Ni(2+), and Zn(2+) metal ions using BEF terpolymer as a ligand. The complexes have been characterized by elemental analy...

Eight isomeric networks based on equimolar terpolymers were synthesized using group transfer polymerization (GTP) and were characterized in terms of their swelling properties. Two hydrophilic monomers, the nonionic methoxy hexa(ethylene glycol) methacrylate (HEGMA) and the ionizable 2-(dimethylamino)ethyl methacrylate (DMAEMA), and a hydrophobic (nonionic) monomer, methyl methacrylate (MMA), we...

Electrically-induced behaviuor was compared in the non-stretched and uniaxially stretched poly(vinylidene fluoride-trifluoroethylenechlorofluoroethylene) terpolymer a member of the relaxor polymer family that exhibits fast response speeds, a giant electrostriction, high electric energy density and a large electrocaloric effect. Although the temperature dependence of the low-field dielectric con...
