Abstract

The development of new polymer materials from renewable sources and less aggressive to the environment has received much attention in recent years, especially the adhesives in aqueous medium that have specific properties of application, lower cost of raw material and less environmental impact. For this purpose, studies demonstrate that the emulsion and miniemulsion polymerization techniques are quite attractive for the production of pressure sensitive adhesives (PSA) using different raw materials from renewable sources. The focus of this project is to develop new PSA adhesives by emulsion and miniemulsion polymerization of ²-farneceno, obtained from renewable sources to substitute the traditional acrylic monomers employed in the production of PSA adhesives, to be applied in the manufacture of adhesive tapes and other adhesive materials of industrial interest. In addition, this project aims to employ different strategies of synthesis to find the best process conditions to produce the PSA adhesives, in addition to evaluating the effect of the concentration of farnecene, initiator and monomer composition on the colloidal properties and adhesive application. The adhesives will be characterized in relation to overall and individual monomer conversion, polymeric composition, colloidal properties (particle diameter, surface tension, zeta potential, coagulum formation), weight-average molecular weights, gel content, rheological behavior, thermal and mechanical properties. The adhesives will be used to produce tapes of biaxially oriented polypropylene films (BOPP) and evaluated in relation to properties of adhesion, cohesion, tack and shear. This project will have the technical support of BASF S.A. for the manufacturing and characterization of adhesives tapes, aiming to understand the effect of farnesene on the colloidal, intrinsic and application properties of "green" PSA adhesives to be applied in the manufacture of adhesive tapes and other adhesive materials.
