The polybutadiene incorporation in waterborne polystyrene nanoparticles by miniemulsion polymerization improves the toughness of the final product. Unfortunately, the polymerization does not proceed to completion, remaining a high level of unreacted monomer. This work addresses the implementation of two post-treatment methods to efficiently remove the residual styrene from polybutadiene/polystyrene latexes with 50% of solid content: i) post-polymerization with redox initiators; and ii) post-polymerization by thermal initiation of styrene at high temperature (≥120 °C). The mechanisms responsible of the effects of both post-treatments on the properties of hybrid materials are here discussed. [ABSTRACT FROM AUTHOR] |
