## Abstract To understand the molecular architectures of styrene‐butadiene four‐arm star (SBS) copolymers, a size exclusion chromatography combined with laser light scattering (SEC‐LLS) has been used to determine their weight‐average molecular weight (__M__~w~) and radius of gyration (〈__S__^2^〉^1/

## Abstract The straightforward synthesis of a polystyrene‐__arm__‐polybutadiene‐__arm__‐poly(methyl methacrylate) triarm star copolymer has been successfully realized by a sequence of reactions which involves the sequential addition of a living polybutadienyllithium to a polystyrene macromonomer w
## Abstract A star‐shape styrene–butadiene–styrene triblock copolymer SBS (802) was synthesized and fractionated into four fractions coded as 802‐F1 (four arms), 802‐F2 (two arms), 802‐F3 (one arm), and 802‐F4 by repeating fractional precipitation. Their weight‐average molecular weight (__M__~w~) w
## Abstract Methacrylic star polymers were synthesized by the “arm‐first” method of star polymer formation by the addition of difunctional monomer, ethylene glycol dimethacrylate, to living linear poly(methyl methacrylate) as prepared by group transfer polymerisation (GTP). The effects of living po
