, p. 55 - 62 (2013)
A series of semi-interpenetrating polymer networks based on linear polyurethane and 1,3-bis(glycidyloxypropyl)-1,1,3,3-tetramethyldisiloxane, which was cross-linked with diethylenetriamine, were obtained. The samples have been submitted to thermal stability investigations at non-isothermal conditions in nitrogen. The kinetic parameters of the degradation process were determined both by isoconversional methods of Friedman and Ozawa-Flynn-Wall as well as by model fitting multivariate non-linear regression method. It was observed that the thermal stability of the semi-interpenetrating polymer networks depends on siloxane content. The best fit of the f(α) function with the experimental data was found for three-step degradation mechanism. Successive stages of thermal decomposition occurred by diffusion, phase-boundary and autocatalysis models, respectively.

FILM FORMING PERSONAL CARE COMPOSITIONS AND METHODS

, (2013/03/26)
Compositions, kits and methods of preparing a biocompatible film for cosmetic or medical uses are disclosed. The compositions or kits contain polyvinyl acetal (PVA), siloxane and a solvent. The siloxane can have a hydrophilic group. Once the solvent content is reduced, for instance, by evaporation, the mixture of PVA and siloxane is solidified, forming a film. The compositions and kits, optionally, further include one or more of an antimicrobial agent, a pigment, an anti-inflammatory agent, an anesthetic agent or a hemostatic agent. Such a film can be used, for example, in the form of an antimicrobial sealant, a liquid bandage, body paints, scar camouflage, water-proof sun block, makeup sealer, or antimicrobial wipe or spray.
