Abstract
A laser light scattering detector with a scattering angle of 90° is attached to a conventional GPC. The reliability of the instrumentation (GPC/LS method) is tested by measuring the molecular-weight distributions of the standard linear polymers with narrow molecular-weight distribution. The applicability of the GPC/LS method for determining the degree of branching is studied by using comb-shaped branched polystyrenes previously characterized. It is concluded that the GPC/LS method is useful for determining the degree of branching if the type of branching is known and also if the degree of branching is not too high.
