“…The intramolecular hydrogen bonding in HEMA (marked by A in the figure) rather easily forms. It has been reported previously 24,25 that this hydrogen bonding of HEMA is quite stable, and the hydroxyl groups in HEMA are unlikely to form intermolecular bonding with other carbonyl groups unless the carbonyl groups have strong attractive forces [e.g., poly(vinyl pyrrolidone) molecules with N next to C¼ ¼O]. There were no such carbonyl groups in the solution systems that we analyzed, so the intermolecular hydrogen bonding of HEMA was negligible.…”

“…A schematic representation of hydrogen bonding from carbonyl and hydroxyl groups of the copolymer is displayed in Figure 5. The stretching bands in the figure were obtained by previous researchers [23][24][25] who also studied the infrared spectra of free and hydrogen-bonded carbonyl groups of MAA and HEMA as well as the intermolecular and intramolecular hydrogen bonding. The FTIR spectra of copolymers with different AVs are shown in Figure 6.…”

The coffee-ring effect of a coated narrow stripe approximately 350 lm wide was examined. The coating solution was based on a new formulation with a specific application for the production of color filters used in liquid-crystal display panels. The basic components of this formulation were color pigments, solvents, and a novel alkali solution resin. The resin was a copolymer consisting of methacrylic acid, hydroxyl ethyl methacrylate, and methyl methacrylate. Three solvents with different boiling points were used: propylene glycol methyl ether acetate, methyl ethyl ketone, and tetrahydrofuran. The formation of a coffee ring on the coated stripe was mainly dependent on the solvent evaporation rate and the acid value of the copolymer. The acid value determined the strength of the hydrogen bonding of the copolymer. Fourier transform infrared analysis revealed that the intramolecular hydrogen bonding of the carbonyl groups of hydroxyl ethyl methacrylate was one of the critical factors affecting the formation of a coffee ring. The other factor was the rate of solvent evaporation. A proper adjustment of the acid value combined with a highly volatile solvent could effectively eliminate the formation of a coffee ring.

Summary:The miscibility and thermal behaviour of binary mixtures of poly(styrene-co-itaconic acid) containing 11 or 27 mol % of itaconic acid (PSIA-11 or PSIA27) with poly(butyl methacrylate) (PBMA)or poly(butyl methacrylate-co-4-vinylpyridine) containing 10 or 26 mol% of 4-vinylpyridine (PBM4VP-10, PBM4V-P26) were investigated by differential scanning calorimetry, scanning electron microscopy, FTIR spectroscopy and thermogravimetry. The results showed that 11 mol % of itaconic acid and 10 mol % of 4-vinylpyridine respectively introduced within the polystyrene and poly(butyl methacrylate) matrices induced the miscibility of this pair of polymers due to specific interactions of hydrogen bonding type with partial pyridine protonation that occurred between the two copolymers as evidenced by FTIR from the appearance of two new bands at 1607 cm À1 and 1640 cm À1 . Increasing itaconic acid content from 11 to 27 mol % led to a decrease of the intensity of the specific interactions within PSIA-27/PBM4VP blends and is attributed to both accessibility and self association effects as evidenced by DSC from the change of the shape of the Tgcomposition curves and by FTIR spectroscopy. As shown from the thermogravimetric study, the presence of these specific interactions delayed the anhydride formation and improved the thermal stability of the blends.
