| Abstract: | Shear modulus-temperature curves and swelling behavior of poly(dimethylsiloxane)-bisphenol-A polycarbonate block copolymers were studied. Two glass transitions corresponding to the silicone and polycarbonate phases are found. A correlation of the shear modulus between the two glass transitions and the swelling ratio of the rubbery phase is suggested. |
