“…Figure 8 shows a DSC plot of neat EEA revealing two endotherms at 51° and 102°C. The endotherm at 102°C is consistent with the T m literature value of EEA of 99°C, while the endotherm at 51°C is related to the Vicat softening temperature 20 . The enthalpy of the cooling exotherm suggests that the crystallinity of the co‐polymer is 14.2%±1.2%, which is consistent with a copolymer with this acrylate content 20 …”

Molded ceramics with simple poly(ethylene-ethylacryate) thermoplastic binders suffer severe distortion during heating associated with relaxation of polymer conformations, but blends of poly(ethylene-ethylacrylate) containing poly(isobutyl methacrylate) resins and polyethylene glycol and mineral additives do not suffer distortions. The polymer blends are characterized using polarized light microscopy and thermal analysis. Crystallinity and spherulite size of the binder are reduced by blending and by the addition of ceramic powder. Plasticizer additives polyethylene glycol and mineral oil phase separate in poly(ethyleneethyacrylate), but are compatablized by additions of poly(isobutyl methacrylate). The compatibalized plasticizers are able to relax the polymer conformations after molding, avoiding distortion on subsequent heating. J ournal

“…Fig 8(A)–8(E) shows the changes in the infrared spectra of the activated sludges from the different treatments. The assignments of the various bands and peaks made in this study are in reasonable agreement with those reported in the literature for similar functional groups [ 37 – 39 ]. The initial sludge and the sludge fed with glucose had the same infrared spectroscopy profile; the bands at 2925 and 2854 cm−1 are, respectively, due to the C-H stretching absorbance of a methyl group and of a methylene group.…”

Polymer nanocomposites have been widely used in the preparation of coating agents in the leather industry. Considering the complex bio-effect and ecological risk of nanomaterial, research on the biodegradability and biocompatibility of polyacrylate/metal nanocomposites in activated sludge system is of specific significance. We investigated the change of the bacterial community and diversity of activated sludge fed with polyacrylate/ZnO nanocomposites in both low (500 mg COD /L) and high (1000 mg COD/L) doses. COD removal, dehydrogenase activity, and total protein of activated sludge system were monitored in all treatments over 30 days. The results demonstrated that the exposure to both polyacrylate/ ZnO nanocomposite and polyacrylate decreased the dehydrogenase activity at early stage comparing to the control, but had no significant influence on COD removal. Overall, the bacterial communities in activated sludge were resistant to polyacrylate/ZnO nanocomposites, and had higher levels of metabolic activity, protein accumulation and bioavailability when exposed to these chemicals comparing to the control especially at later stages of incubation (15–30 days), which indicated that these polyacrylate/ZnO nanocomposites of certain amount were biocompatible to activated sludge system.

Thermogravimetric analysis is used to examine the degradation of a multicomponent polymer binder consisting of a blend of a polyethylene co‐ethyl acrylate with a polyisobutymethacrylate polymer. In the polymer blends without ceramic powder, the methacrylate component degrades at a temperature lower than the ethylene copolymer. Minor additives polyethylene glycol, stearic acid, and paraffinic mineral oil are also considered. The thermal degradation of a five‐component blend is only approximately as expected from the individual components, with retardation of the methacrylate degradation. Oxide ceramic powder significantly alters polymer degradation, retarding degradation in the early stages but accelerating degradation in the later exothermic stages. Polymer–polymer interactions and oxide–polymer interactions make the degradation behavior of blends difficult to predict from single component behavior.
