El crecimiento en los extremos: reactividad de grupos terminales en polmeros para la sntesis de copolmeros bloque

José E. Báez

Three different cases of reactions using end-groups in polymers were analyzed for the synthesis of block copolymers, such as: a) azide (R N3) and alkine (R C CH) end groups to obtain a 1,3-dipolar cycloaddition (click chemistry), b) ,-hydroxy telechelic polymers (HO R OH) and diisocyanates (OCN R NCO) to synthesize polyurethanes by polycondesation and c) alkyl halides (R Cl or R Br) to prepare block copolymers derived of polystyrene by atom transfer radical polymerization (ATRP).

Es el profesor de Qumica tambin profesor de Lengua?

Juan Quílez Pardo

This article analyses the importance of the language of chemistry in the construction, communication and learning of this scientific subject. Some of the most relevant difficulties of the language of chemistry are highlighted. Among them we can find the high number of new terms as well as their different types, and also the scarce attention given by textbooks to the meaningful learning of new vocabulary. To these problems it must be added the lack of opportunities that students experience to produce scientific arguments in the chemistry classroom, which certainly is connected with the difficulty they face to develop higher order thinking skills. Some recommendations are suggested in order to improve the ability of students when talking, thinking, reading and writing chemistry.
