This invention provides block copolymers containing ester linkages and polymerized units of ethylenically unsaturated monomers and a process for their preparation. The process is characterized by polymerizing an ethylenically unsaturated monomer in the presence of Lewis Acid and an acid polyhalide to give a omega , omega ''-dihalopolymer, which is then converted by hydrolysis into omega , omega ''-dihydroxypolymer, which is, directly or indirectly in the form of its ester, polymerized with a polycondensable monomer such as a diol, and its ester; dicarboxylic acid, its ester, its halide; hydroxy carboxylic acid, and its ester, to give the block copolymer. The new polymers are useful for applications in which polyesters of special properties are required. These new polymers are useful for many practical applications, since they can be cast or spun into films, fibers, plastics, etc., depending upon their compositions and types of monomer. For example, polystyrene ethylene terephthalate can be used as a plastic in a richer composition of styrene units, and as a fiber or as a film in a richer composition of ethylene terephthalate units.
