Wettability and thermal analysis of hydrophobic poly(methyl methacrylate)/silica nanocomposites

open access: yesAdsorption Science & Technology, 2017
Hydrophobic poly(methyl methacrylate)/silica layers on the glass support activated with plasma were obtained. Wettability was investigated from the contact angle measurements and surface free energy estimation by means of using contact angle hysteresis ...

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

Temporal Augmentation With Methyl Methacrylate [PDF]

open access: yesAesthetic Surgery Journal, 2011
Concavity in the temporal area reflects a deficiency in the bulk of the temporalis muscle or overlying temporal fat pad. It may be a reflection of senescence, low body fat, exaggerated adjacent skeletal or soft-tissue contours, idiopathic progressive atrophy, or postsurgical deformities. The authors describe the application of methyl methacrylate (MMA)

Fate of methyl methacrylate in rats [PDF]

open access: yesBritish Journal of Cancer, 1977
Up to 88% of a single dose of methyl[14C]methacrylate in rats is expired as 14CO2 in 10 days (65% in 2 h), irrespective of the route of administration and of the specific labelling of the propylene residue of the molecule. The implications of this observation, and of the excretion of small amounts of [14C]methylmalonate, [14C]-succinate and probably of

3D Micro/Nanopatterning of a Vinylferrocene Copolymer

open access: yesMolecules, 2020
In nanoimprint lithography (NIL), a pattern is created by mechanical deformation of an imprint resist via embossing with a stamp, where the adhesion behavior during the filling of the imprint stamp and its subsequent detachment may impose some practical ...

The Synthesis and Characterization of Poly(methyl methacrylate-tourmaline acrylate)

open access: yesAdvances in Materials Science and Engineering, 2016
In order to synthesize the tourmaline-containing functional copolymer, the polymerizable organic tourmaline acrylate was prepared by the surface modification on tourmaline powder and then copolymerization with methyl methacrylate to get poly(methyl ...
