Imada, Motosuke published the artcileCopolymers incorporated with β-substituted acrylate synthesized by organo-catalyzed group-transfer polymerization, Application of Methyl 3-phenyl-2-propenoate, the publication is Polymer Journal (Tokyo, Japan) (2021), 53(9), 989-999, database is CAplus.
Various copolymers incorporated with β-substituted acrylates, such as alkyl crotonates (e.g., Me crotonate (MC), Et crotonate (EC), iso-Pr crotonate (iPC), and Bu crotonate (nBC)) and Me cinnamate (MCin), were synthesized by group-transfer polymerization (GTP) using a silicon-based Lewis acid catalyst. In addition to β-substituted acrylates, α-substituted acrylates (e.g., Me methacrylate (MMA) and Bu methacrylate (nBMA)) were examined as comonomers. Proton NMR (1H NMR) spectroscopy and matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF-MS) characterizations of the obtained copolymers revealed that each monomer component was incorporated sufficiently. The thermal stabilities of the resulting copolymers were investigated by dynamic mech. anal. (DMA), indicating that the glass-transition temperature (Tg) of the copolymers can be widely varied over a relatively high-temperature range by selecting the optimal comonomer. More specifically, the Tg values of poly(MC-random-EC) (MC/EC molar ratio = 50/50), poly(MC-random-nBC) (MC/nBC molar ratio = 50/50), poly(MC-random-MCin) (MC/MCin molar ratio = 54/46), and poly(nBC-random-MCin) (nBC/MCin molar ratio = 56/44) were 173, 130, 216, and 167°C, resp.
