14 Aug 1978TL;DR: In this paper, a cured adhesive composition possessing excellent cohesive strength at high temperatures along with excellent shear strength and solvent resistance is prepared by the electron beam initiated curing of an adhesive composition comprising selectively hydrogenated monoalkenyl arene/conjugated diene block copolymer component, tackifying resin and a di-to-tetra functional acrylate or methacrylate selected from the group consisting of acrylic and methacrylic acid esters of polyols.

TL;DR: This study investigates the structural features of porcine gastric mucin in aqueous dispersions and its interactions with water-soluble polymers using isothermal titration calorimetry, turbidimetric titration, dynamic light scattering, and transmission electron microscopy.
Abstract: This study investigates the structural features of porcine gastric mucin (PGM) in aqueous dispersions and its interactions with water-soluble polymers (poly(acrylic acid) (PAA), poly(methacrylic acid) (PMAA), poly(ethylene oxide), and poly(ethylene glycol)) using isothermal titration calorimetry, turbidimetric titration, dynamic light scattering, and transmission electron microscopy. It is established that PAA (450 kDa) and PMAA (100 kDa) exhibit strong specific interactions with PGM causing further aggregation of its particles, while PAA (2 kDa), poly(ethylene oxide) (1 000 kDa), and poly(ethylene glycol) (10 kDa) do not show any detectable effects on mucin. Sonication of mucin dispersions prior to their mixing with PAA (450 kDa) and PMAA (100 kDa) leads to more pronounced intensity of interactions.

TL;DR: In this paper, a method of preparing acrylic acid or methacrylic acid by catalytic gas-phase oxidation of C3/C4 alkanes, alkenes, alkanols and/or alkanals and precursors thereof is described.
Abstract: Disclosed is a method of preparing acrylic acid or methacrylic acid by: (a) preparing a gaseous product mixture having essentially the composition of a reaction mixture of catalytic gas-phase oxidation of C3/C4 alkanes, alkenes, alkanols and/or alkanals and/or precursors thereof to form acrylic acid or methacrylic acid, characterized by (b) condensation of the product mixture, (c) crystallization of the acrylic acid or methacrylic acid from the solution obtained in stage (b), and (d) extraction of the resulting crystals from the mother liquor.
