Linear and cyclic amphiphilic block copolymers consisting of poly(ethylene oxide) (PEO) as the hydrophilic segment and poly(methyl acrylate) or poly(ethyl acrylate) as the hydrophobic segments were synthesized and self-assembled to form flower-like micelles. The micelles from linear (methyl acrylate)12(ethylene oxide)73(methyl acrylate)12 (Mn = 1000-3200-1000, l-MOM) showed a cloud point (Tc) a...

Acrylate is produced in significant quantities through the microbial cleavage of the highly abundant marine osmoprotectant dimethylsulfoniopropionate, an important process in the marine sulfur cycle. Acrylate can inhibit bacterial growth, likely through its conversion to the highly toxic molecule acrylyl-CoA. Previous work identified an acrylyl-CoA reductase, encoded by the gene acuI, as being ...

Herein, mono- and disubstituted thioxanthones have been synthesized introduced as photosensitizers of iodonium salt for cationic free-radical photopolymerization epoxy an acrylate monomer, respectively. Photoinitiation activity these molecules was verified during processes performed upon exposure to visible LEDs 420, 455, 470 nm. The kinetics the followed using FT-IR spectroscopy. Moreover, dev...

Starch graft poly(methyl acrylate) (S-g-PMA) was prepared by ceric ion initiation of methyl acrylate in an aqueous corn starch slurry (prime starch) which maximized the accessibility of the starch for graft polymerization. A new ceric ion reaction sequence was established as starch-initiator-methyl acrylate followed by addition of a small amount of ceric ion solution when the graft polymerizati...

In order to improve the performance of allyl starch-g-poly(acrylic acid-co-acrylate) sizes, effect of molecular structure of the acrylate monomers grafted onto allyl starch has been studied. A series of acrylates including methyl acrylate (MA), ethyl acrylate (EA), butyl acrylate (BA) and 2-ethylhexyl acrylate (EHA) have been grafted onto allyl starch with the same degree of substitution throug...

The development of new polymerizable lyotropic liquid crystals (LLCs) utilizing charged amphiphilic molecules such as those based on long chain imidazolium compounds, is a relatively new design direction for producing robust membranes with controllable nano-structures. Here we have developed a novel polymerizable ionic liquid based LLC, 1-hexadecyl-3-methylimidazolium acrylate (C16mimAcr), wher...

Multiple insertions of acrylate in copolymerization with ethylene, and an insertion homo-oligomerization of methyl acrylate were observed for the first time. Key to these findings, and to mechanistic insights reported, are labile-substituted complexes as catalyst precursors.

In this work, electro-responsive shape-memory actuators were developed by incorporating a conductive heater in dual-curing thiol-acrylate-epoxy polymer (SMP). A heater, consisting of an electrically silver-ink track printed on Kapton® substrate, was assembled to the SMP, taking advantage processing. The effect (SME) activated heat dissipated Joule track. Boron nitride agglomerates dispersed lay...

Amphiphilic hairy nanoparticles are prepared in a one step, batch, heterogeneous polymerization of styrene or n-butyl acrylate, using a water-soluble poly(sodium acrylate) alkoxyamine macroinitiator based on the SG1 nitroxide.
