High tg acrylate
WebFeb 6, 2004 · The high molecular weight polyacrylate self-emulsifying emulsion with 20% hydroxyl monomer and 50% solid content was prepared. Waterborne polyester was used to modify the acrylate resin. Webmaterials with high modulus and low elongation. Acrylic acrylate films were so brittle that it was impossible to measure their physical-mechanical properties. Polyether urethane acrylates had high elongation but undesirable high weight loss at 205°C. Aromatic urethane acrylate exhibited low modulus and high weight loss similar to PEUA-2.
