24. Lignin and Soy Oil-Derived Polymeric Biocomposites by “Grafting from” RAFT Polymerization
“Grafting from” RAFT polymerization was carried out on lignin using three soybean oil-derived methacrylate monomers toward sustainable biocomposites. These grafted biocomposites showed structure-dependent thermal and mechanical properties. The presence of hydrogen bonding between secondary amides resulted in grafted copolymers with much higher glass transition temperature a...

A novel architecture toward third-generation thermoplastic elastomers by a grafting strategy.
Thermoplastic elastomers (TPEs) are ever sought using a simple robust synthetic approach. Widely successful first-generation TPEs rely on microphase-separated ABA triblock copolymers (Architecture I). Recent multigraft copolymers represent the second-generation TPEs in which multiple branched rigid segments are dispersed in a rubbery backbone matrix (Architecture II). This paper r...

Monte Carlo Simulation of the Grafting of Maleic Anhydride onto Polypropylene at Higher Temperature
The graft of maleic anhydride (MAH) onto isotactic polypropylene (iPP) initiated by dicumyl peroxide (DCP) at 190 °C was studied by means of the Monte Carlo method. The ceiling temperature theory, i.e., no possibility for the homopolymerization of MAH to occur at higher temperatures, was used in this study. The simulation results show that most MAH monomers were grafted onto the radical chai...

Grafting of maleic anhydride onto linear polyethylene: A Monte Carlo study
Monte Carlo simulation was used to study the graft of maleic anhydride (MAH) onto linear polyethylene (PE-g-MAH) initiated by dicumyl peroxide (DCP). Simulation results revealed that major MAH monomers attached onto PE chains as branched graft at higher MAH content. However, at extremely low MAH content, the fraction of bridged graft was very close to that of branched graft. This conclusi...

125. A Novel Architecture toward Third-Generation Thermoplastic Elastomers by a Grafting Strategy
摘要：一直以来，科研工作者们都在寻求如何使用简单高效合成方法来制备性能优异的热塑性弹性体。第一代成功的热塑性弹性体是基于微相分离的ABA三嵌段共聚物 (Architecture I)。近年来，将刚性支链分散在橡胶主链基体中形成了第二代热塑性弹性体 (Architecture II)。在本文中，我们阐述了基于将刚性主链分散在接枝的橡胶基体中的第三代热塑弹性体(Architecture III)这个想法。这类第三代热塑性弹性体将无规共聚物作为侧链, 可以制备...

164. Functionalization of graphene and grafting of temperature-responsive surfaces from graphene by ATRP "on water".
Water-dispersible graphene with temperature-responsive surfaces has successfully been synthesized by grafting poly(N-isopropylacrylamide) (PNIPAM) from graphene via surface-initiated atom transfer radical polymerization (ATRP). First, graphene surfaces are functionalized with aminophenol groups by diazonium reaction on water. Subsequently, bromoisobutyrate groups are covalently attached to the phe...

Self-organized ordered microporous thin films from grafting copolymers
Highly ordered porous films of cellulose-based graft copolymers were prepared by the breath figure method upon solvent evaporation. The morphology of the microporous films was investigated by scanning electron microscopy (SEM) and atom force microscopy (AFM). The influences of the preparing conditions, the length and the type of the side chains of copolymers on the morphology of the porous fi...

129. Grafting polyamide 6 onto multi-walled carbon nanotubes using microwave irradiation.
Chemical reactions under microwave irradiation can be very efficient,with a significant shortening of reaction time. Few studies have reported the use of microwaves to functionalize carbon nanotubes. In the work reported, a new method of formulating functionalized multi-walled carbon nanotubes (MWNTs) was developed by covalent grafting of polyamide 6 (PA6) chains onto the carbon nanotubes assisted...

The role of grafting degree in the dispersion of silica/polyacrylate nanocomposite particles into polyacrylate matrix
A series of “guava-like” silica/polyacrylate nanocomposite particles with different grafting degrees were prepared via mini-emulsion polymerization. The silica/polyacrylate composite particles were melt-mixed with unfilled polyacrylate (PA) resin to prepare the corresponding silica/polyacrylate molded composites, and the dispersion mechanism of these silica particles from the “...
