Abstract

A silylated polycarbonate comprises silylated carbonate units, where the silylated carbonate units can be derived from a silylated dihydroxy aromatic compound of the formula (1a):wherein Ga and Gb are each independently C1-12 alkyl, —OSi(C1-12 alkyl)3, C1-12 arylalkyl, or —OSi(C1-12 arylalkyl)3; Za and Zb are each independently a straight or branched C2-18 alkylene, a C8-18 arylalkylene, or a C8-18 alkylarylene, Xa is a direct bond, a heteroatom-containing group, or a C1-18 organic group, and r and s are each independently 1 or 2. A method of forming the silylated dihydroxy aromatic compound, and for forming the silylated polycarbonate, are disclosed. Also disclosed is a thermoplastic composition comprising the silylated polycarbonate, and an article comprising the thermoplastic composition.
