Abstract

As sustainability concerns increase, the need to explore new biobased monomers arises. In this work, latexes with high biobased (61–71 %) and solids content (up to 40 %) are produced by emulsion polymerization for their application as coatings. Initially, the emulsion homopolymerization of three different soft biobased methacrylates is investigated; 2-octyl methacrylate (OMA), tetrahydrogeraniol methacrylate (TGM) and tetradecyl methacrylate (TDM). The challenges to polymerize these monomers by emulsion polymerization are addressed and the properties of the homopolymers obtained measured (T_g and molar masses). Secondly, the three different soft biobased methacrylates are copolymerized by seeded semibatch emulsion polymerization with tetrahydrofurfuryl methacrylate (THFM) which is a hard and more hydrophilic biobased monomer. It is observed that by increasing THFM content the incorporation of the hydrophobic monomers is facilitated. Among the different synthesized copolymers, OMA/THFM 87/13 wt% and TGM/THFM 41/59 wt% present good film forming properties, suitable mechanical properties and better water resistance than a petroleum-based methyl methacrylate/butyl acrylate (MMA/BA) copolymer.

期刊介绍： The aim of this international journal is to analyse and publicise the progress and current state of knowledge in the field of organic coatings and related materials. The Editors and the Editorial Board members will solicit both review and research papers from academic and industrial scientists who are actively engaged in research and development or, in the case of review papers, have extensive experience in the subject to be reviewed. Unsolicited manuscripts will be accepted if they meet the journal''s requirements. The journal publishes papers dealing with such subjects as: • Chemical, physical and technological properties of organic coatings and related materials • Problems and methods of preparation, manufacture and application of these materials • Performance, testing and analysis.
