This study examines the influence of different cellulose treatments, including coating by latex or by grafting with polymer/vinyl monomers, as well as with various additive dispersants (e.g., stearic acid or anhydrides) and coupling agents (e.g., maleic anhydride, abietic acid, and linoleic acid). The mechanical properties are examined for poly(vinyl chloride) treated hardwood (chemithermomechanical pulp and sawdust). In most cases, properties are improved compared with untreated composites. Among all methods, grafting was found to be the most effective. Coupling agents show better performance compared with dispersants. Linoleic acid is believed to be the best coupling agent.
