Abstract

A method for preparing block copolymers from which can be made transparent blue articles comprising sequentially charging under polymerization conditions at least one monovinylaromatic monomer and at least one conjugated diene monomer, wherein at least the first monomer charge is a monovinylaromatic monomer. charge polymerized in the presence of an initiator; wherein at least one other charge polymerized in the presence of an initiator is a monomer selected from the group of conjugated dime monomers and mixtures of monovinylaromatic and conjugated dime monomers; wherein the final monomer charge is a conjugated diene charge; and thereafter charging the reaction mixture with at least one coupling agent. The invention copolymers are particularly useful for applications such as packaging, display devices, toys and decorative items in which transparent blue appearance is desired without significant compromise of other physical and mechanical properties.
