019. A multiscale scheme for simulating polymer Tg
All-atomistic (AA) molecular dynamics (MD) is considered as one of the desirable methods for studying glass transition temperatures (Tg) of specific polymers. However, heavy computational efforts are generally required, and the simulated Tg values are not always in good agreement with the experimental data. In this work, a multiscale scheme is proposed: first, the structural and volumetric prope...

Cyclic polymer with alternating monomer sequence
Cyclic polymers with alternating monomer sequence are synthesized for the ? rst time based on the ring-closure strategy. Well-de? ned telechelic alternating polymers are synthesized by reversible addition–fragmentation chain transfer polymerization by copolymerizing the electron acceptor monomer of N -benzylmaleimide and donor monomer of styrene with a feed ratio of 1 between them. The corr...

The introduction of the Barbier reaction into polymer chemistry
The Barbier reaction, a widely utilized reaction for carbon–carbon bond formation, has played important roles in modern organic chemistry for more than a century. Here, we show its successful introduction to polymer chemistry. Through one-pot Barbier polyaddition (both A2+B2 type and AB type) of monomers containing an organic halide and a benzoyl group, a series of phenylmethanol group containi...

Lanthanum containing polymer''s modification to PP
Polypropylene (PP) ''s low impact strength limits its usages. Adding some a rare
earth polymer can enhance PP''s tensile strength and impact strength. Acrylic
lanthanum was prepared by the reaction between lanthanum oxide and acrylic acid.
The IR spectrum prove that and optimum reacting conditions are that the bulk
ratio of La(AA)3 and MMA is not less than one and temperature is about 80℃.
L...

Electroconductive natural polymer-based hydrogels
Hydrogels prepared from natural polymers have received immense considerations over the past decade due to their safe nature, biocompatibility, hydrophilic properties, and biodegradable nature. More recently, when treated with electroactive materials, these hydrogels were endowed with high electrical conductivity, electrochemical redox properties, and electromechanical properties; consequently, for...

Influence of Branching Architecture on Polymer Properties
Hyperbranched polymers (HBPs), invented at the end of 1980s, are one important subclass of the fourth generation macromolecular architectures following the linear, branched, and crosslinking polymers. Due to their unique topological structure and interesting physical/chemical properties, HBPs have attracted wide attention from both academia and industry. HBPs are composed of linear units, dendri...

Journal of Biomaterials Science, Polymer Edition 1999, 10(4), 501-512
polycaprolactone/poly(ethylene oxide) polylactide tricomponent copolymer (PCEL) with different compositions were synthesized by copolymerization of caprolactone and L-lactide in the presence of poly(ethylene glycol) using stannous octoate as a catalyst. The copolymers were purified and characterized by various analytical techniques such as GPC, FT-IR. 1H NMR, 13C NMR, DSC and X-ray diffractometry....
