Abstract The article discusses the centrality of emotions in the educational proposal for Social Work at Universidad del Quindío, specifically in the academic spaces of Contemporary Social Work II and III, aimed towards professional praxis training with subjects and families. It presents the foundations of the pioneers that back this training proposal and the teaching-learning strategies implemented to materialize it in the approach of the dimensions of the discipline-profession, from a commitment with the students' reflexivity as subjects, with emotions constructed and transformed into significant interactions, particularly family ones.

Resumo O artigo expõe o lugar central das emoções na proposta educacional do Serviço Social da Universidad del Quindío, especificamente nos espaços acadêmicos do Serviço Social Contemporâneo II e III, voltados à formação para a práxis profissional com sujeitos e famílias. Apresentam-se as contribuições das pioneiras que sustentam esta proposta de formação, e as estratégias de ensino e aprendizagem implementadas para concretizá-la na abordagem das dimensões da disciplina profissão, a partir de um compromisso com a reflexividade dos(as) estudantes de si mesmos(as) como sujeitos, com emoções construídas e transformadas em iterações significativas, principalmente familiares.

In this paper, we report the synthesis of polystyrene end- capped with three- short- arm PDMS (PS-(PDMS)3) using poly(styrene – co–vinyltriethoxysilane) copolymers as precursors. These materials were obtained in a two-step process; first, two random copolymers of poly(St –co – VTES) having different molecular weight, and vinyltriethoxysilane content were prepared via free radical polymerization. The materials thus obtained, were treated with an excess of dimethyldimethoxysilane to produce PS-(PDMS)3 by co-condensation of alkoxysilane groups. The formation of the copolymers was confirmed by proton nuclear magnetic resonance, infrared spectroscopy, and gel permeation chromatography. Surface properties of films formed by casting the copolymers on a glass sheet were studied by Atomic force microscopy (AFM), and water contact angle measurements. We found that PS-(PDMS)3 copolymers exhibit a hydrophobic behavior, showing water contact angles close to values early reported for block copolymers composed by PS and PDMS segments, and comparable with the corresponding value of PDMS.
