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

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)

Control of optical and mechanical properties of poly(methyl methacrylate) by introducing lithium salt [PDF]

open access: yes, 2018
We investigated the effect of lithium trifluoromethanesulfonate (LiCF_3SO_3) on the optical properties of poly(methyl methacrylate) (PMMA), known as a glassy transparent polymer.

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 ...
