Fundamental Modeling of Solid-State Polymerization Process Systems for Polyesters and Polyamides
… solid-state polymerization process systems of condensation polymers, particularly poly(ethylene terephthalate) and nylon-6. The work centers on an approach for modeling commercial-scale, as opposed to laboratory-scale, systems. The focus is not solely on coupled polymerization and diffusion, …

Synthesis of Higher Molecular Weight Poly(D-glucaramides) and Poly(aldaramides) as Novel Gel Forming Agents
… requirement for higher molecular weight condensation polymers. The salts were prepared by treating monopotassium D-glucarate with H<super>+</super> form ion exchange resin to give D-glucaric acid, which was then reacted with a diamine. The glucarate portion of the salt was activated for …

Internal surface coating and photochemical modification of polypropylene microfiltration membrane
… is generally applicable and can be used to coat condensation polymers to the internal membrane surface as an even thin layer, without significantly changing the morphology of the polyolefin microfiltration membranes.</p> <p>The chemical functionality of polysulfonamide coated membrane surface …

Analysis of organosilicone surfactants and their degradation products
… with longer EO chain products more stable as low condensation polymers and silanols, and short EO chains more commonly observed in cyclic products. The GC/MS analysis of the heptane-soluble fraction of acid-degraded Silwet L-77 enabled the tentative assignment of the cyclic trimer, 27 [R¹, R², R³ …
