Unusual Contributions of Molecular Architecture to Rheology and Flow Birefringence in Hyperbranched Polystyrene Melts

With the increase in sophisticated synthesis methods, it appears that polymer architecture may be a tunable property. Therefore, the role of architecture in rheological and processing properties has received renewed attention, mainly because of dendrimer synthesis and metallocene-catalyst technology. Linear polymers and hyperbranched polymers represent two… CONTINUE READING
