Abstract Mouthguards are polymeric devices recommended to be used by athletes help prevent orofacial injuries. Some of the problems described when using mouthguards can addressed producing customized with thinner walls additive processing techniques. In present work, new materials for this application, such as poly(lactic acid) (rPLA) recycled from food packaging, poly(methyl methacrylate) (PMM...

The reaction of alkaline 2,4-dihydroxyquinoline 1 and 1-tetralone 2 in 2% sodium hydrox­ ide solution with vinyl acetate afforded a brown solid 3, which on treatment with phospho­ rous oxychloride yielded 2,4-dichloro-3-[l’-(l-chloro-naphth-2-yl)ethyl]quinoline (4). The same reaction of 1 and chromanone 7 with vinyl acetate afforded 2,4-dichloro-3-[l’-(4-chloro2-methyl-chromen-3-yl)ethyl]quinol...

−− Time optimal monomer and reactor temperature set-point profiles were computed and implemented experimentally for the control of copolymer composition and minimization of reaction time in emulsion copolymerization systems. Iterative Dynamic Programming (IDP) was used for the offline calculation of the optimal profiles. This approach can deal with constrained optimization of systems described ...
