, p. 475 - 479 (2013)
Some acrylate monomers have been synthesized and copolymerized by means of free radical polymerization with methyl methacrylate and butyl methacrylate. These monomers are known to introduce the desired functionality and tune the properties of the resulting polymer. The synthesized monomers and the polymers have been characterized with NMR spectroscopy. The latter is utilized to study the polymer composition and verify the distribution of the monomers in the copolymer chain. The reactivity ratios have been estimated and concluded moderately random distribution of the monomers in the copolymer chain.

Cu(OTf)2-catalyzed diarylation of activated alkenes by using diaryliodonium(III) salts has been developed. With this method, arylated oxindoles can be easily accessed in good yields. Insights into the mechanism of copper-catalyzed arylations are discussed, and the findings are expected to help increase the level of understanding of catalytic arylations with diaryliodonium salts.

Fast synthesis employing a microwave assisted neat protocol of new monomers potentially useful for the preparation of PDLC films
Barros, M. Teresa,Mouquinho, Ana I.,Petrova, Krasimira T.,Saavedra, Mara D.,Sotomayor, Joao C.
experimental part, p. 557 - 566 (2012/04/10)
It has been repor ted that the length of the molecular chain and the rigidity of molecules influence the structure of the polymer network in PDLC films and hence the electro-optical proper ties of the composites. Herein, a series of new aromatic monomeric monomethacrylates, bismethacrylates and monovinylbenzene derivatives with a mesogenic core were successfully synthesized under microwave irradiation. The microwave assisted synthesis resulted in decreased reaction times, reduced solvent requirement, increased operational simplicity, and in most cases, improved yields and selectivity.

Films based on new methacrylate monomers: Synthesis, characterisation and electro-optical properties
Mouquinho, Ana,Saavedra, Mara,Maiau, Alexandre,Petrova, Krasimira,Barros, M. Teresa,Figueirinhas,Sotomayor, Joao
scheme or table, p. 132 - 140 (2012/01/06)
A number of liquid crystal monomers based on methacrylate derivatives were synthesised by novel mild and solventless procedures under microwave irradiation. Their photo- and thermo assisted homo- and co-polymerizations with glycidyl methacrylate were investigated. The resulting polymers were characterised by NMR, GPC, DSC, and SEM to determine their structures and properties. The effects of the structures of the monomers on the electro-optical properties were correlated. Copyright Taylor & Francis Group, LLC.
