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:

Optimising Drug Solubilisation in Amorphous Polymer Dispersions: Rational Selection of Hot-melt Extrusion Processing Parameters
TL;DR: To ensure formation of a binary amorphous drug dispersion at a specific composition, HME processing temperatures should at least be equal to, or exceed, the corresponding temperature value on the liquid–solid curve in a F–H T–ϕ phase diagram.

Temperature dependence of the fracture behavior of nylon 6/ABS blends
TL;DR: In this paper, the effect of temperature (from 25 to −25°C) and specimen ligament length on the fracture energy, obtained from an instrumented drop tower test, of two compatibilized nylon 6/ABS blends (40 and 25 ¼wt% ABS) and the neat ABS was investigated.

Nanosilica-reinforced UV-cured polyurethane dispersion
TL;DR: In this paper, the effects of hydrophobic and hydrophilic modified silicas were studied with dispersion and dispersion cast films and it was found that particle size increased and water swell decreased, tensile modulus, strength, and thermal stability increased with the addition and increasing amount of silica.

Tamper resistant dosage form comprising an anionic polymer
TL;DR: In this article, a pharmaceutical dosage form exhibiting a breaking strength of at least 500 N, said dosage form containing - a pharmacologically active ingredient (A); - a physiologically acceptable polymer (B) obtainable by polymerization of a monomer composition comprising an ethylenically unsaturated monomer bearing an anionic functional group, in protonated form or a physically acceptable salt thereof.

Predictions of viscoelastic strain rate dependent behavior of fiber-reinforced polymeric composites
TL;DR: In this paper, a viscoelastic damage model for aligned and 3D randomly oriented discontinuous fiber-reinforced polymeric composites is proposed, based on a combination of the Laplace-transformed superposition principle and the ensemble-averaged micromechanics.
