Influence of the Poly(ethylene Glycol) Methyl Ether Methacrylates on the Selected Physicochemical Properties of Thermally Sensitive Polymeric Particles for Controlled Drug Delivery

N-isopropylacrylamide and poly methyl ether methacrylates were synthesized by surfactant-free precipitation polymerization using ammonium persulfate at 70 °C. 77. 54, 45. 10, 6. 80, 92. 95 u00b1 1. 56, respectively, in the 18/u2013B0C range, which were determined by dynamic light scattering, were at 18. 00 : 05. 54, 58. 01, 68. 12, and 61. 90 %, respectively. We conclude that the length of the co-monomer chain nonlinearly influences the stability of the fabricated thermosensitive polymer nanostructures.

Mesoporous Silica and Oligo (Ethylene Glycol) Methacrylates-Based Dual-Responsive Hybrid Nanogels

Hydrodynamic diameters at various temperatures were measured by dynamic light scattering, and cloud point temperatures were determined by turbidimetry. Cell viability in fibroblast and human prostate cancer cell lines were determined by a standard colorimetric assay. The polymeric structure of hybrid nanogels was optimized to include high percentages of acidic co-monomer, retaining homogeneous nanosize distribution, achieving optimal volume transition temperature values for biomedical applications, and outstanding pH response. Even at the highest nanogel concentration, cell viability was above 80%, according to the cytotoxicity assays.

Lyophilic and Sorption Properties of Chitosan Aerogels Modified with Copolymers Based on Glycidyl Methacrylate and Alkyl Methacrylates

This paper explores the influence of copolymers made from glycidyl methacrylate and alkyl methacrylates with C6-C18 hydrocarbon side groups on the wettability and sorption characteristics of surface-modified chitosan aerogels on surface-modified chitosan aerogels' wettability and sorption characteristics. However, this process takes longer than unmodified chitosan aerogels based on glycidyl methacrylate and alkyl methacrylates; however, unlike unmodified chitosan, the reaction has a longer induction period.

Pyrolysis of Copolymers Based on Alkyl Methacrylates with C 1 -C 8 Alkyl Chain

The manuscript describes pyrolysis of copolymers based on a C 1 -C 8 alkyl chain at temperatures between 250 °C and 400 °C, which was investigated using pyrolysis-gas chromatography. In this case, alkyl methacrylate copolymers' key thermal degradation products are monomers, as alkyl methacrylate copolymers' main thermal degradation products are monomers, alkyl methacrylates used by synthesis.

Assessment of thermal damage in polymethyl methacrylates using quasi-static components of ultrasonic waves

Abstract The use of an acoustic nonlinear response can be a cost-effective tool for early stage damage evaluation of samples. The Quasi-static component of damaged structures, which also includes the high sensitivity of acoustic nonlinearity and low attenuative behavior, has a strong potential for early-stage damage analysis in highly attenuating materials, and it could be used for early-stage damage evaluation in highly attenuating materials. An experimental method for specifically detecting the QSC pulse of ultrasonic wave tone burst is suggested in this paper. Although a high-frequency longitudinal wave transducer is used for the initial ultrasonic wave tone burst, the co-propagating QSC pulse is captured using a low-frequency ultrasonic transducer. Experimental findings show that the QSC generation of ultrasonic wave propagation may be a promising alternative for investigating thermal degradation of highly attenuating materials.

Effect of the Composition of Copolymers Based on Glycidyl Methacrylate and Fluoroalkyl Methacrylates on the Free Energy and Lyophilic Properties of the Modified Surface

This research shows that to minimize surface free energy, the surface free energy can be reduced by using reactive copolymers based on glycidyl methacrylate and fluoroalkyl methacrylates with low fluorine content in the monomer unit. It's also shown that copolymers based on glycidyl methacrylate and fluoroalkyl methacrylates can be used to produce self-cleaning polymer coatings.
