Biography

Paul Pineda Contreras is currently working on his PhD at the University of Bayreuth (Germany) under the supervision of Prof. Seema Agarwal, focusing on the photo-polymerization of novel low-shrinking resins. He received his BSc and MSc degree from the University of Marburg in 2010 and 2012, respectively. During his undergraduate studies, he made a research internship in Prof. Susanta Banerjee's group at the Indian Institute of Technology (IIT) Kharagpur on PPX modified poly(arylethere)s. After that he received his research initiative a scholarship of the Bayer-Science Foundation. His research interests are photo-polymerization techniques, materials characterization, composites and coatings.

Abstract

Cyclic monomer systems that can undergo a radical-ring opening polymerization (RROP), such as vinylcyclopropane (VCP) derivatives are highly interesting monomer resins, providing lower-volume shrinkage on polymerization than other vinyl monomers, like methacrylates. Especially among electronics, coatings, lithography, dental applications and 3D microstructures highly specified resins with low volume shrinkage are fundamental to match the precise specifications adapted for the final end-use. Thereby, cross-linkable VCP resins are currently accessing a variety of precise specifications within a wide spectrum of applications, in industry as well as in research. Thus we developed a universal concept based on selective intermolecular interactions, applying VCP resins as fast curable, low-shrinking, high-performance resin. Herein we focused on the monomer synthesis as well as on the development and characterization of a modular construction kit based on VCPs. To provide a powerful illustration, diversified resins were prepared and analyzed. Hereby, we could show an excellent control of high reactivity, nearly regardless of the chosen spacer-unit. With an appropriate variation of spacer-unit selective characteristics, like e.g. mechanical strength, thermal stability and optical refraction could be adjusted in a simple and suitable way, making the system adaptable to any use. These results are highlighted in this presentation and offer the system an outstanding prospective within various applications.
