Characterization and Process

Our interest is focused on several aspects of polymeric-based materials where basic research, materials and processes design and applications are combined. Overall, we address problems related with polymer synthesis, characterization of molecular structure, polymer processing and end-product properties. In our view, the basic knowledge at the molecular level is key to properly approach the challenges found in engineering processing or product design.

From a fundamental point of view, we pursue a deeper understanding of the factors that control structure and polymer chains dynamics at molecular level. We pay particular attention to mixtures of homopolymers and copolymers as they potentially offer a much wider range of properties and performance to those found in single homopolymers. We study the processes of phase separation in supercritical fluids that lead to thermoplastic foams, massively used in thermal and acoustic insulation. We also study crystallization, adhesion and degradation mechanisms in polyolefins, which have a large impact in their lifetime use. The group employ experimental tools that include the advanced use of viscoelastic, calorimetric and microspectroscopic-based techniques. In many cases, experimentation is complemented by numerical modeling, carried out either within the group or in association with other areas.

This basic knowledge is applied in solving many practical problems, from simple characterization of raw materials to the development of polymers for specific applications. The group produces polymers at both, laboratory and pilot plant scale; develops specific technologies for thermoplastics processing such as injection for large pieces or production of expanded polyolefins. The group also develops technologies for the production of a wide range of materials so diverse as proppants agents used in fracture of non-conventional oil wells or speciality elastomers for satellite fuel containers. Our skills have helped to several local industries in the challenge of replacing imported parts and products by local counterparts, or in meeting international standards to facilitate their possible access to external markets.
