Homogeneous polymerization of hydrophobic monomers in a bio-based dl-menthol/1-tetradecanol eutectic mixture by ATRP and RAFT polymerization

A bio-based eutectic mixture, composed of dl-menthol and 1-tetradecanol, was investigated for the first time as solvent for the homogeneous ATRP and RAFT polymerization of different hydrophobic monomers.

The Influence of Crown Ether and Alcohol on Unsaturation and Molar Mass of Poly(propylene oxide)s Prepared by Use of Potassiumt-Butoxide: Reinvestigation of Chain Transfer Reactions

Potassiumt-butoxide dissolved in tetrahydrofuran effectively initiates homogeneous polymerization of propylene oxide at room temperature. Unsaturation and molar mass (Mn) of the polymers prepared depend on the presence of additives, such as macrocyclic ligand 18-crown-6 (L) andt-butanol. Application of the ligand alone results in distinct increase of unsaturation and decrease ofMn, whereas use oft-BuOH leads to simultaneous decrease of unsaturation andMn. Activation oft-BuOK/t-BuOH system with the ligand causes further decrease of unsaturation, that is, from 12.0 to 3.5 mol % for OK/OH (1/3) and OK/OH/L (1/3/2) systems, respectively. Unexpectedly,Mnof the polymers obtained does not practically change (~4800). This result differs from that reported earlier for neat PO polymerization initiated potassium 1-methoxy-2-propoxide/1-methoxy-2-propanol, in which in the presence of the same ligandMnincreases to ~12 400 for the same ratio of reagents. The mechanism of studied processes was discussed.
