“…To put our results on ASE syntheses in context, we note that Bajaj et al26, 27 synthesized P(MAA‐EA) latex particles with various weight ratios of MAA/EA ranging from 53/47 to 83/17. They carried out semicontinuous emulsion polymerization at 50 °C with a preemulsion of MAA and EA stabilized with SDS and Hydroxide AAO (a nonionic surfactant produced by Hico Products), initiated with a redox system of potassium persulfate/sodium metabisulfate.…”

We describe the synthesis and characterization of a weakly cross-linked poly(methacrylic acid-co-ethyl acrylate) alkali-swellable emulsion (ASE), as well as an investigation of its influence on the rate of polymer diffusion in latex films. The films examined were formed from poly(vinyl acetate-co-butyl acrylate) latex particles containing a small amount of acrylic acid as a comonomer. Polymer diffusion rates were monitored by the energy transfer technique. We found that the presence of the ASE component, either in the acid form or fully neutralized by ammonia or sodium hydroxide, had very little effect on the polymer diffusion rate. However, in the presence of 2 wt % NH 4 -ASE, there was a small but significant increase in the polymer diffusion rate. V V C 2005 Wiley Periodicals, Inc.

Various control interventions have been effective in the control of arthropod vectors to a certain extent; still, sustained vector control is an existing problem globally. Insecticide-based formulations have been found to be useful, however the proper delivery of active molecules to target vectors is important. Currently, synthetic pyrethroid deltamethrin (DM) has been microencapsulated in the emulsion paint binder and evaluated for long-term effectiveness against dengue vector Aedes aegypti. Different compositions of emulsion binder were prepared by varying the content of monomer and DM. A selection was made for the composition yielding the best combination of properties like solid content, intrinsic viscosity, and DM content. Developed formulation was tested against laboratory-reared and pathogen-free Ae. aegypti mosquitoes. Encapsulation of DM in emulsion binder during polymerization showed a uniform distribution. The optimized formulation was stable and did not have a considerable plasticizing effect. Scanning electron microscopy revealed that grain-like micro crystals of DM and surfactant sodium lauryl sulfate (SDS) were uniformly distributed on the formulation surface. The best optimized formulation was highly effective against dengue vector Ae. aegypti and found to provide efficacy for up to 18 months of application. The knockdown time (KDT) values KDT10 and KDT50 were 7.4 min (95% CI: 5.6–9.1) and 22.1 min (95% CI: 19.7–24.3) respectively, whereas 24 h corrected mortality was 90% (95% CI: 82.5–97.5) after 18 months of application (T18). The probit model used to determine knockdown values did not deviate from the linearity and displayed normal distribution of knockdown % with time for different formulations (p ≥ 0.1). Presently developed DM microencapsulated emulsion binder was stable, smooth, and uniform. The binder displayed excellent anti-insect property and was capable of providing long-term effectiveness against dengue vectors Ae. aegypti. Such a formulation after field-scale evaluation could be very useful in attaining long-term protection from arthropod vectors.

“…The observed FTIR band positions and their assignments are presented in Table 2. In pure film a strong band observed at 1452 cm −1 has been assigned to bending mode of vibration corresponding to CH 3 group, while another strong band observed at 1492 cm −1 has been attributed to C-H bending of CH 2 [20,21]. The FTIR absorption bands attributed to carbonyl stretching of the acid and ester units have appeared as weak bands at 1601 cm −1 range [17].…”

Pure and different concentrations of Mn 2+ (1.0, 2.0, 3.0, 4.0 and 5.0 mol%) doped PVA/MAA:EA polymer blend films were prepared by solution casting method. The structural analysis of the prepared samples by X-ray Diffraction reveals broadening of diffraction peak which implies a lower degree of crystallinity with higher Mn 2+ concentration. UV-Vis spectral analysis shows a significant red shift in the optical band gap with increase in Mn 2+ concentration. FTIR spectrum exhibits bands characteristic of stretching and bending vibrations O-H, C-H, C=C and C-O groups and the changes in the FTIR spectrum with dopant concentration indicate the complexation of dopant with the polymer blend. The conductivity study shows that the doping of Mn 2+ ions into the polymer blend system enhances its ionic conductivity from 2.46 X 10 -8 Scm -1 for pure film to 1.41 X 10 -7 Scm -1 for 5 mol% of Mn 2+ ions at room temperature, which is due to the increase in mobile charge carriers and their increased mobility which is explained in terms of an increase in the amorphicity.
