    Notes: Summary Copolymers of methyl acrylate (MA) with an electron-donor comonomer (N-vinylcarbazole) (NVC) are mixed with copolymers of methyl methacrylate (MMA) with a electron-acceptor comonomer (2-(3,5-dinitrobenzoyl) oxyethyl methacrylate) (DNBM) such that 1:1 mol ratios of NVC:DNBM are present at all times. The blends obtained are phase separated up to an average of 27 mol% donor/acceptor structural unit in the copolymer. Above 27 mol% “perturbation”, poly(MA) and poly(MMA) become compatible.

    Compatibilization of poly(methyl acrylate) and polysterene through charge transfer interactions (1991)

    Notes: Summary Two incompatible copolymers, poly(methyl acrylate) and polystyrene have been compatibilized through charge transfer interactions. Methyl acrylate was copolymerized with an electron donor and styrene was copolymerized with an electron acceptor. Interaction between the electron donor, N-vinylcarbazole, and the electron acceptor, 2-((3,5-dinitrobenzoyl) oxy) ethyl methacrylate was sufficiently strong to overcome the reluctance to mix when interactive group concentrations were above 12 mole%.

    Notes: The microstructure of a series of high conversion copolymers of methyl acrylate (MA) and N-vinylcarbazole (NVC) was characterized by NMR. 1H- and 13C-NMR spectra were assigned by comparison to the homopolymers and by using heteronuclear shift correlation spectroscopy. MA-centered triad distributions were obtained from the carbonyl carbon. Distributions of NVC sequences were determined from aromatic carbons 1 and 8a, and aromatic proton 1 These experimentally determined sequence distributions were compared to those calculated from reactivity ratios approximated from the copolymer compositions. Agreement was very good for low NVC content copolymers. Three signals were particularly useful in providing rapid assessment of the distribution of NVC units within low NVC content copolymers: proton 1 and carbon 1 of NVC and the carbonyl carbon of MA. © 1992 John Wiley & Sons, Inc.
