1. ROMP como um método versátil para a obtenção de materiais poliméricos diferenciados
Ring Opening Metathesis Polymerization (ROMP) of cyclic olefins is a powerful transition metal-catalyzed reaction for syntheses of polymers and copolymers. The key feature of this reaction is the [2+2]-cycloaddition mechanism, with retention of the olefinic unsaturation in the polymer chain and occurrence of living polymerization. With the development of met

2. Síntese e caracterização de macrômeros e copolímeros de óleo de semente de seringueira / Synthesis and characterization of macromers and copolymers of rubber seed oil
A procura de novos materiais poliméricos oriundos de matérias primas renováveis é de grande importância científica, tecnológica e ambiental, dado que elas podem substituir as de origem na cadeia do petróleo, além de contribuir para a diminuição de gases de efeito estufa e o acúmulo de lixo plástico. Os óleos vegetais são matérias primas renov

3. Preparation and bactericidal effect of composites based on crosslinked copolymers containing silver nanoparticles
Commercial copolymers based on styrene and divinylbenzene containing sulfonic acid groups were used as support for the incorporation of silver nanoparticles. These nanoparticles were obtained in situ by the reduction of Ag+ by using hydroxylamine in the presence of a protective agent. These materials were characterized with determination of the silver conten

4. Electrophoresis in lyotropic polymer liquid crystals
Excellent electrophoretic separations of a variety of biological molecules can be accomplished by using uncharged, triblock copolymers as the “gel” media. These copolymers form uncrosslinked, lyotropic liquid crystalline phases of large micelles between which molecules must travel. Unlike crosslinked hydrogels in common use, these alternative media have

5. Synthesis and characterization of a model extracellular matrix that induces partial regeneration of adult mammalian skin.
Regeneration of the dermis does not occur spontaneously in the adult mammal. The epidermis is regenerated spontaneously provided there is a dermal substrate over which it can migrate. Certain highly porous, crosslinked collagen-glycosaminoglycan copolymers have induced partial morphogenesis of skin when seeded with dermal and epidermal cells and then grafted
