On the Assembly of Actin Polymerization‐Powered Motors

Macromolecular Rapid Communications, EarlyView.
Actin polymerization‐powered motors have the highest speed when the actin recruiting‐polymerizing proteins are immobilized in polymer brushes on their surface. These motors orbit around larger tracer particles at pH above the isoelectric point of ActA but dock onto the tracer particles’ surface at lower pH. ABSTRACT Nano‐ and micromotors are a class of

A PLP‐SEC Investigation of Di(Ethylene Glycol) Methyl Ether Methacrylate Radical Polymerization Propagation Kinetics in Solution

Macromolecular Reaction Engineering, EarlyView.
The propagation rate coefficient of di(ethylene glycol) methyl ether methacrylate exhibits the same temperature dependency but is a factor of 12 higher in aqueous solution compared to bulk. Smaller increases are observed in ethanol and ethanol/water mixtures, with the value of the rate coefficient decreasing as the monomer concentration in solution is ...

The mechanism of interaction between chlorhexidine digluconate and poly(2-hydroxyethyl methacrylate)

, 1981
The extent of the interaction between chlorhexidine digluconate and poly(2-hydroxyethyl methacrylate), (PHEMA), is independent of temperature between 22–50 °C which is consistent with an ion-ion interaction mechanism.

Quantification of Homopolymer Impurities in Structured Acrylate Copolymers Produced by High‐Temperature Semi‐Batch Radical Polymerization

Macromolecular Reaction Engineering, EarlyView.
Isobornyl acrylate macromonomer solutions are synthesized via high‐temperature radical polymerization using a starved‐feed semi‐batch operating policy. Through sequential feeding, the macromonomer solution functions as an addition‐fragmentation agent, facilitating the production of blocky and comb acrylate copolymers.

Concentration effects in the base-catalyzed hydrolysis of oligo(ethylene glycol)- and amine-containing methacrylic monomers

Designed Monomers and Polymers, 2017
Concentration effects in the base-catalyzed hydrolysis of water-soluble methacrylates (3-(N,N-dimethylaminoethyl) methacrylate (DMAEMA), 2-hydroxyethyl methacrylate (HEMA) and oligo(ethylene glycol) methacrylates (OEGMAs)) have been studied.

Unsaturated biobased polyesters from bicyclic α‐pinene‐based diols

Polymer International, EarlyView.
We present the synthesis of four biosourced unsaturated polyesters made from chiral terpene‐based diols and esters of renewable diacids. The resulting materials harbor a bicyclic pinene ring in their backbones which leads to enhanced thermal properties while still conferring susceptibility to enzyme hydrolysis for chains having a cis alkene.
