Principles of polymer engineering
TLDR
In this article, the elastic properties of polymeric solids and their properties of rubber are discussed. But they focus on the structure of the molecule rather than the properties of the solids.Abstract:

Viscoelastic behaviour of pumpkin balloons
TL;DR: In this article, a simulation of the viscoelastic behavior of balloon lobes was performed using the finite element software ABAQUS, and it was shown that time-dependent effects in a balloon structure can lead to significant stress redistribution and large increases in the transverse strains in the lobes.

Glass transition in polymers: (In)correct determination of activation energy
Roman Svoboda,Jiří Málek +1 more
TL;DR: In this paper, the authors investigated the possibility of applying Kissinger-type equations for the evaluation of apparent activation energy in the case of the glass transition phenomenon and found that the values determined by these equations were in major disagreement with the original values of Δh∗ used as the input data for the simulations.

Tamper-resistant dosage form containing ethylene-vinyl acetate polymer
TL;DR: A tamper resistant, oral pharmaceutical dosage form comprising a pharmacologically active ingredient having psychotropic action and an ethylene-vinyl acetate (EVA) polymer which provides resistance against solvent extraction, resistance against grinding, and resistance against dose-dumping in aqueous ethanol was proposed in this article.

Differences in the viscoelastic features of white and grey matter in tension.
TL;DR: Owing to its higher stiffness, white matter can absorb more energy than grey matter at strain rates of 0.025, 0.15 and 0.25 /s in tension, as evidenced by differential scanning calorimetry and Fourier transform infrared spectrometer spectra.
