Studies On Butyl Acrylate Modifier And Properties Of Its Blends

When the traditional metal materials were gradually replaced by polymer materials, we realized the significance of plastic and rubber in our life. The perfect features of plastics should be maintained, just like their corrosion resistance, easy processing, however, the drawbacks of plastics must be concerned. How do we make the biggest limitation to balance the plastics and metal materials? There are various factors that affect constrain from synthesis to processing.The study of modifier, we should make efforts to reduce the negative in terms of the amount and impact. Currently, the core-shell modifier has higher efficiency. During the whole process, there have many factors that affect the results, just like particle size, reaction temperature, shear rate, and testing method. This paper aims to modify SAN resin and polybutylene terephthalate.1. The flocculation easily take place during Internal II and Internal III due to excessive heat released. In a certain range, as the contents of initiator increased, the starting of heating time occurred earlier and the particle size decreased.2. Binding the second chapter, the core-shell particles prepared having different induction periods of modified SAN resin. With the growth of PBA induction period, SAN/PBA-g-SAN impact value blends first increased gradually smaller. When the induction period is26min, the blends impact value is the maximum of413J/m.3. Epoxy-functionalized PBA-g-SAN (PBA-g-SAG) was prepared with emulsion polymerization method and glycidyl methacrylate (GMA) was introduced to the shell of PBA-g-SAN. The reactions between the epoxy groups and PBT were used to compatibilize the PBT/PBA-g-SAN blends.
