  • I am looking for diacrylates with longer hydrocarbon segments so that they are more compatible with poly E/B - the C10 and C12 analogs of HDDA are compatible with poly E/B and I found one that is commercially available : decamethylene glycol diacrylate (I ordered a sample from ABCR GmbH) I still need to find dodecylmethylene glycol diacrylate.
  • These monomers are more compatible with the Polymer that I tried: KG1657 (it is more desirable because it is a commercial grade for them) Anyway, EDF8323 gives clearer formulations with HDDA Next: polymerize with an initiator the urethane acrylate and take a RI (compare with Asahi and our plates) run IRs of the SEBS and SIEBS (it arrived) and compare with Asahi clear.
  • Press plates with the new SIEBS in combination with our monomers (should be more compatible) 3.
