Abstract
In this paper, hydroxyl terminated polysiloxane was first prepared by ring-opening polymerization of octamethylcyclotetrasiloxane (D4), which was then modified with acryloyl chloride to obtain acryloyloxy polysiloxane. A light-scattering material was synthesized by copolymerization of acryloyloxy polysiloxane and methyl methacrylate (MMA). The results showed that the transmittance of the material was 88% and the haze was 93% when the ratio of MMA to light-scattering agent was 100:1, the amount of initiator was 0.3%, and the post-polymerization temperature was 50 °C. The TGA data indicated that the material had excellent heat resistance. Therefore, it has a wide range of applications in the field of light-emitting diodes.
