Abstract

The aim of this work was to improve the interfacial adhesion between the matrix and the wood particles in polypropylene based wood plastic composites with the addition of chemical agents at the wood particle surface. We found, that with the addition of rather small, linear molecules, e.g. ε-Caprolactone, interfacial adhesion, and therefore tensile strength, was improved up to 10% additionally to the benefits of a common maleic anhydride based compatibilizer. Furthermore, we found that also the chemical composition of the molecules added at the surface shows an influence at the extent of the improvement.
