The thermal degradation of poly(iso-butyl methacrylate) and poly(sec-butyl methacrylate) [PDF]

open access: yesJournal of the Serbian Chemical Society, 2000
The non-oxidative thermal degradation of poly(iso-butyl methacrylate) and poly(sec-butyl methacrylate) was investigated by studying changes in the polymer residue. Due to the different number of β-hydrogens in their ester substituents, these two

Damping Analysis of Some Inorganic Particles on Poly(butyl-methacrylate). [PDF]

open access: yesMaterials (Basel), 2018
Viscoelastic polymers can be used as damping materials to control unexpected vibration and noise through energy dissipation. To investigate the effect of an inorganic filler on damping property, a series of inorganic particles, Ferriferous oxide(Fe3O4), Graphene/Fe3O4(GF), and Fe3O4 of demagnetization(α-Fe2O3) were incorporated into poly(butyl ...

Fluorescence Analysis of Local Microenvironments in Polymer Films Using Solvatochromic Dyes [PDF]

open access: yesSensors
Polymer films and polymer blend films are widely used as functional materials; however, their photophysical behavior cannot be fully explained solely by bulk properties such as relative permittivity or glass transition temperature.

The successful impossible radical ring-opening copolymerization of thionolactones and methacrylates via an auxiliary third comonomer [PDF]

open access: yesNature Communications
Polymethacrylate derivatives are widely used in various industrial applications. The incorporation of degradable thioester bonds in polymethacrylates to achieve degradability/recyclability upon disposal is a challenge.

Reprogrammable Hydroplastic Latex Films and Water‐Driven Phase Separation [PDF]

open access: yesAdvanced Science
Thermoplastics are a class of plastic polymers that can be remolded repeatedly by heating and cooling. Recently, inspired by the concept of thermoplastics, hydroplastic materials, a type of materials that can be reshaped with the aid of water, have ...

Hot-melt extruded ibuprofen ternary solid dispersions using in-line UV–Vis: Impact of an ionizable polymer on thermodynamics and dissolution [PDF]

open access: yesInternational Journal of Pharmaceutics: X
Amorphous solid dispersions (ASDs) remain a key strategy for enhancing the dissolution of poorly soluble APIs. Building on previous work with binary ibuprofen (IBU) blends, this study investigates the impact of incorporating poly(butyl methacrylate-co-(2-

Nanostructure of PMMA/MAM Blends Prepared by Out-of-Equilibrium (Extrusion) and Near-Equilibrium (Casting) Self-Assembly and Their Nanocellular or Microcellular Structure Obtained from CO2 Foaming

open access: yesNanomaterials, 2021
Blends of poly(methyl methacrylate) (PMMA) and a triblock copolymer poly(methyl methacrylate)-b-poly(butyl acrylate)-b-poly(methyl methacrylate) (MAM) have been obtained following both out-of-equilibrium (extrusion) and near-equilibrium (solvent casting)

Comparison of the protective efficiency of polymethacrylates with different side chain length for AA2024 alloy

open access: yesJournal of Materials Research and Technology, 2021
The protective properties of polymethacrylate coatings with different side chain lengths for 2024 aluminum alloys were studied, focusing on the chain length increase but also on the Ar-plasma pretreatment applied to the metal surface.
