Butyl Methacrylate → HCID 131734312, compound

Participants

Reaction Steps

Desired stoichiometric quantities of N,N-dimethylaminoethyl methacrylate (DMAEMA), propylacrylic acid (PAA), and butylmethacrylate (BMA) were added to poly(DMAEMA) macroCTA dissolved in N,N-dimethylformamide (25 wt % monomer and macroCTA to solvent). For all polymerizations [M]o/[CTA]o and [CTA]o/[I]o were 250:1 and 10:1 respectively. Following the addition of V70 the solutions were purged with nitrogen for 30 min and allowed to react at 30° C. for 18 h, copolymering the included monomers to form the [DMAEMA/PAA/BMA] random copolymer block. The resultant diblock copolymers were isolated by precipitation into 50:50 v:v diethyl ether/pentane. The precipitated polymers were then redissolved in acetone and subsequently precipitated into pentane (×3) and dried overnight in vacuo.
