Abstract: Many of the polymers used in composite systems and in other applications are cross-linked or thermoset polymers. How do such cross-linked polymers differ in properties from the better-understood linear or thermoplastic polymers? This review paper attempts to answer this question. The paper is written from the practical viewpoint of the experimental scientist who is using cross-linked polymers but who is not an expert on the theory of cross-linking. In spite of their intractable nature once they have been formed, and the difficulty of fabricating highly cross-linked polymers, such materials have some outstanding properties that make them ideal for many applications. The properties include (1) excellent dimensional stability and low creep rates, (2) resistance to solvents, and (3) in many cases, high heat-distortion or softening temperatures.

Fabrication, characterization and drug loading efficiency of citric acid crosslinked NaCMC-HPMC hydrogel films for wound healing drug delivery applications.
K. Dharmalingam,R. Anandalakshmi +1 more
TL;DR: It was found that swelling degree, crystallinity and water contact angle of hydrogel films based on NaCMC-HPMC (2wt%) decrease with increase in CA from 5% to 20% (by weight) and that the prepared hydrogels can be used as potential wound healing materials.

TL;DR: In this article, an isothermal time-temperature-transformation (TTT) cure diagram for thermosetting systems has been developed to aid in the understanding of the cure process and the properties after cure, which summarizes in a convenient manner the temperature of cure (Tcure) vs. the times to gelation, vitrification, phase separation, full cure, and thermal degradation.

The Phenomena of Rupture and Flow in Solids
TL;DR: In this article, the authors investigated the effect of surface scratches on the mechanical strength of solids, and some general conclusions were reached which appear to have a direct bearing on the problem of rupture, from an engineering standpoint, and also on the larger question of the nature of intermolecular cohesion.
