CHARACTERIZATION OF POLY(DIMETHYL SILOXANE)-POLYCARBONATE BLOCK COPOLYMERS.
Abstract
Shear modulus-temperature curves and swelling behavior of poly(dimethyl siloxane)-bisphenol-A polycarbonate block copolymers were studied. Two glass transitions corresponding to the silicone and polycarbonate phases are found. The dependence of one phase transition on the presence of the second phase is discussed. A correlation of the shear modulus between the two glass transitions and the swelling ratio of the rubbery phase is suggested. (Author)
