| Abstract: | Macroporous P(VAc-co-TAIC) resin beads were prepared by suspension polymerization.The influences of the amount of crosslinking agent and porogen and bead diameter on pore volume and porosity were investigated.The results show that pore volume and porosity increase with increasing the bead diameter and content of porogen.The airborne acoustic absorption coefficients of the composites composed of PU/EP blend matrix and the resin beads were measured by using transfer function method,and the results show that t... |
