Acrylate monomer reactivity studied through time resolved laser spectroscopy
نویسندگان
چکیده
The acrylate radicals produced by addition of aminoalkyl radicals to an acrylate unit were directly observed by transient absorption spectroscopy. These acrylate radicals are characterized by a strong absorption in the visible region of the spectrum allowing an easy study of their chemical reactivity. Therefore, a new method for the determination of both the addition and recombination rate constants is proposed. These radicals being particularly important as possible representative of polymerization propagating radicals, this approach appears powerful and promising to study the reactivity of different monomers and to determine both propagation and termination rate constants of radical polymerization.

Synthesis and characterization of organotin containing copolymers: reactivity ratio studies.
Organotin monomers containing dibutyltin groups--dibutyltin citraconate (DBTC) as a new monomer and dibutyltin maleate (DBTM)--were synthesized. Free radical copolymerizations of the organotin monomers with styrene (ST) and butyl acrylate (BA) were performed. The overall conversion was kept low (< or = 15% wt/wt) for all studied samples and the copolymers composition was determined from tin ana...

A silver-acrylate nanocomposite was prepared using a novel one-pot strategy involving eosin dye as visible sensitizer and an amine derivative as radicals source. The mechanism highlighted by steady state photolysis and time resolved absorption spectroscopy lies on the initial formation of a strong ion pair complex between eosin and Ag + . Upon visible irradiation, the excited triplet state of t...

Liquid crystal (LC) monomers are a novel type of resin for stereolithography that result in polymers having unique physical and mechanical properties. These monomers consist of rigid central cores connected to acrylate functional groups by short aliphatic chains. Because of the rigid-rod structure of the monomer the cross-linked polymer networks formed have high glass transition temperatures (T...

This work presents a new method to prepare poly(sodium acrylate) magnetite composite nanoparticles. Core/shell type magnetite nanocomposites were synthesized using sodium acrylate as monomer and N,N-methylenebisacrylamide (MBA) as crosslinker. Microemulsion polymerization was used for constructing core/shell structures with magnetite nanoparticles as core and poly(sodium acrylate) as shell. Fou...
