| Abstract: | Thermal expansion coefficient and dynamic mechanical properties in terms of the storage modulus E′, loss modulus E" and the loss tangent of a crosslinked multiblock copolymer of hydroxy-terminated polybutadiene and polymethyl methacrylate were investigated. E′ and E" were calculated according to the single relaxation time model.The thermodynamic parameters were presented. The molecular weight between crosslinking points MC was calculated about 945. The characteristic damping behavior shows that this polymer is a semicompatible multiblock copolymer with excellent mechanical damping. |
