ABSTRACT A lactose-containing monomer, N-(2-lactosylethyl)acrylamide, was synthesized and polymerized with N-hydroxyethyl acrylamide and 1 wt % of N, N'-methylenebis(acrylamide) and potassium persulfate as the initiator to produce hydrogels. The weight percent of N-(2-lactosylethyl)acrylamide were increased from 0 to 100% in increments of 10%. Hydrogels were successfully produced with up to 90 wt % of N-(2-lactosylethyl)acrylamide. Gelation was confirmed by inverted vial tests and rheology measurements. The as-prepared hydrogels were used for papain stabilization against heat burden and papain that was loaded into hydrogels showed 45% more activity after heating as compared to papain that was heated without hydrogel stabilization. This hydrogel stabilization technique has potential applications in preserving enzyme activity. © 2016 Wiley Periodicals, Inc. J. Polym. Sci., Part A: Polym.

Shape-persistent arylenevinylene macrocycles (AVMs) were successfully prepared in one step from readily available aromatic diene monomers through olefin metathesis in good yields. 1H NMR, UV-Vis absorption and fluorescence studies revealed the aggregation behavior of the obtained macrocycles. SEM characterization showed AVM nanofibril formation. [ABSTRACT FROM AUTHOR]
