Copolymerization of cyclic esters, epoxides and anhydrides: evidence of the dual role of the monomers in the reaction mixture

Florence Isnard、Mario Carratù、Marina Lamberti 等 5 位作者2018-01-01Catalysis Science & Technology

A block copolyester derived from ROCOP of CHO/SA followed by ROP of ε-CL was obtained from the mixture of monomers. The lactone comonomer acts as an endogen cocatalyst during the SA/CHO ROCOP step and as a monomer during ROP.

Reversible thermosalience of 4-aminobenzonitrile

Lukman O. Alimi、Dewald P. van Heerden、Prem Lama 等 5 位作者2018-01-01Chemical Communications

Crystals of 4-aminobenzonitrile grown by sublimation undergo reversible thermosalient phase changes during cooling and subsequent heating. Single-crystal diffraction studies have been carried out at 20 K intervals during cooling from 300 to 100 K in order to explain the structural change that occurs.
