Synergistic reinforcement of a reversible Diels–Alder type network with nanocellulose

Autor: Giada Lo Re, Anna Peterson, Manta Roy, Julia Fagerlund, Christian Müller

Publikováno v: Materials Advances. 2:5171-5180

Covalent adaptable networks are attractive intermediates between thermosets and thermoplastics. To achieve an optimal combination of dimensional stability at the temperature of use and macroscopic flow at elevated temperatures, materials that combine

Use of Bis(pyrrolidone)-Based Dicarboxylic Acids in Poly(ester–amide)-Based Thermosets: Synthesis, Characterization, and Potential Route for Their Chemical Recycling

Autor: Sanjay Rastogi, Carolus H. R. M. Wilsens, Manta Roy, Nils Leoné

Publikováno v: ACS Sustainable Chemistry & Engineering, 7(9):10.1021/ acssuschemeng.9b00850, 8842-8852. American Chemical Society

In this study, we report on the synthesis and characterization of thermosets based on the renewable N,N′-octamethylene-bis(pyrrolidone-4-carboxylic acid) (BP-C8) and 1,3-bis(4,5-dihydro-2-oxazolyl)benzene (IAox). The BP-C8, having two pyrrolidone r

Effect of ionic liquids on the RAFT polymerization of butyl methacrylate

Autor: Arunjunai Raja Shankar Santha Kumar, Manta Roy, Nikhil K. Singha

Publikováno v: European Polymer Journal. 107:294-302

Ionic liquids (IL) were used as solvents to study the RAFT polymerization of butyl methacrylate. The ILs offered a significant increase in the rate of polymerization and the RAFT agents contributed to a tailor-made polymer with controlled molar mass
