| Résumé : |
This study proves that solutions of styrene maleic anhydride copolymers are effective dispersants for C5 and polyterpene resins and can lower the surfactant demand. XIRAN® styrene maleic anhydride copolymers with higher maleic anhydride content lead to increased grinding efficiency and lower particle size. The grinding efficiency increases and viscosity decreases when the molecular weight of the copolymer is lower. Aqueous sodium salts had a higher grinding efficiency than their ammonium counterparts, while higher pH resulted in smaller particle size. In addition, the blending of a higher maleic anhydride/low Mw copolymer with a lower maleic anhydride/high Mw provided the lowest viscosity systems. Styrene maleic anhydride copolymers are ideal for producing ready to use tackifier dispersions, which can be incorporated into water-based adhesives. Being a polymer, styrene maleic anhydride improves dispersion stability compared to traditional monomeric surfactants and is REACH exempt. Moreover, green the molecular structure of styrene maleic anhydride Polyscope Polymers believes that the resulting formulations have improved water resistance and there is less leaching compared to the ones made with traditional monomeric surfactants. |
