VISIOMER® Methacrylates for Impact Modifiers Used in Plastic & Rubber
Emulsion polymers with a crosslinked core are used in a wide variety of applications. The crosslinkers selected and the applied process have an influence on the final polymer properties. VISIOMER® AMA is an asymmetric crosslinker featuring one methacrylate and one allyl group, or two different polymerizable groups of different reactivities. It is used to covalently crosslink the shell with the core of an emulsion polymer. The crosslinking efficiency also depends on the polymerization process. In standard batch processes, symmetric crosslinkers like VISIOMER® EGDMA are most efficient. In a semibatch process, the efficient primary incorporation of the methacrylic group of VISIOMER® AMA combined with delayed crosslinking of the less reactive allyl group results in a high crosslinking efficiency. One major application of core-shell emulsion polymers are impact modifiers.
