Menthyl metacrylate (MnMA) was polymerized both by free radical and anionic initiators in order to obtain polymers with low (poly-MnMA-rad) and high (poly-MnMA-an) isotactic content, respectively, and their VCD spectra were measured as CCl4 solutions between 1650-850 cm-1.Common growth of all VCD intensities, observed in the spectrum of poly-MnMA-an, indicate more and/or longer helical segments.The VCD spectra also revealed that the vibrations of the chain are most sensitive to changes in stereoregularity.

Shifting from petrochemical feedstocks to renewable resources can address some of the environmental issues associated with petrochemical extraction and make plastics production sustainable. Therefore, there is a growing interest in selective methods for transforming abundant renewable feedstocks into monomers suitable for polymer production. Reported herein are one-pot catalytic systems, that are active, productive, and selective under mild conditions for the synthesis of copolymers from renewable materials. Each system allows for anhydride formation, alcohol acylation and/or acid esterification, as well as polymerization of the formed (meth)acrylates, providing direct access to a new library of unique poly(meth)acrylates.

Optically-active, amhiphilic, water-soluble free-radical addition copolymers and their use in the resolution of racemic mixtures
-
, (2008/06/13)
Optically-active, amphiphilic, free-radical addition copolymers having an optically-active hydrophobic portion and an ionic hydrophilic portion are effective resolving agents. This utility is based on a unique combination of properties, viz., water solubility, chirality and amphiphilicity, i.e., having a dual hydrophobic and hydrophilic nature.
