Thermoresponsive property of well-defined poly(N-methyl-N-n-propylacrylamide) and its copolymer architectures prepared by hydrosilylation-promoted group transfer polymerization

Organoboron-mediated polymerizations

“…28B). Chen [124][125][126] and Kakuchi [124][125][126][127][128][129] made outstanding contributions by applying organoboron-mediated group transfer LPP to the polymerization of acrylic esters and acrylamides.…”

Precision synthesis for well-defined linear and/or architecturally controlled thermoresponsive poly(N-substituted acrylamide)s

“…Poly(N,N-dialkylacrylamides)s (PDAs), such as poly(N,Nethylmethylacrylamide) (PEMA), 62,63 poly(N,N-diethylacrylamide) (PDEA), [64][65][66] poly(N-acryloylpyrrolidine) (PAPy), 67 and poly(N-acryloylpiperidine) (PAPi) 67 also show phase-transition behaviors. Recently, we added poly(N,N-isopropylmethylacrylamide) (PiPMA) 68 and poly(N-methyl-N-n-propylacrylamide) (PMnPA) 69 to the repertoire of such compounds.…”

“…A similar tendency has been reported for PDAs such as PEMA, 63 PDEA, 66 and PMnPA. 69 In the next section, we describe the exception that PAMs and PDAs with strong hydrophobic end-groups show the "proportional" relationship between M and T cp .…”

“…The amounts and localized positions of the thermoresponsive and water-soluble units were also important in the PMnPA/PDMA system prepared by hydrosilylation-promoted organocatalyzed GTP. 69…”

Thermoresponsive property of poly(N,N-bis(2-ethoxyethyl)acrylamide) and its multiblock copolymers with poly(N,N-dimethylacrylamide) prepared by hydrosilylation-promoted group transfer polymerization

“…[1][2][3][4][5][6][7][8] For example, aqueous solutions of certain polymers exhibit reversible phase transition behavior, turning turbid when heated to a temperature above the lower critical solution temperature (LCST) and turning back to a clear solution upon dissolution when cooled below the LCST. [9][10][11][12][13][14] One of the molecular design approaches adopted in the synthesis of thermoresponsive polymers is to balance the water solubility and hydrophobicity of the polymers. [15][16][17] Among representative thermoresponsive polymers such as poly(N-substituted (meth)acrylamide), polyethers, and cellulose derivatives, poly(N-isopropylacrylamide) (PNIPAM) has shown potential for chemical and biological applications in controlled drug delivery, bioconjugation, tissue engineering, and bioseparation, as well as in biosensors.…”
