In this paper, we examine the melt rheology of well-defined, model polymers where the long chain branching (LCB) is precisely known from the synthesis. All of these are made by the hydrogenation of polybutadiene, but they vary greatly in the level an

In this report, we highlight the development of polymers as 1D photonic crystals and subsequently place special emphasis on the activities in self-assembled block copolymers as a promising platform material for new photonic crystals. We review recent

Semidilute solutions of ultrahigh molecular weight diblocks in a nonselective good solvent allow investigation of the dynamic structure factor S(q,t) by photon correlation spectroscopy for wavevectors q in the vicinity (and on both sides) of the maxi

The mean-square displacement, Δr2, of very high molecular weight diblock copolymers in solutions near the disorder-to-order transition is investigated by pulsed-field-gradient NMR. The thermodynamic potential influencing the motion leads to a time-i

We describe the synthesis and characterization of a number of polymers with well-defined structures that serve as models for polyethylene with long chain branching. All of them have been made by using anionic polymerization techniques and controlled

Using optical birefringence, small-angle neutron scattering, and field-theoretic methods, we study the effects of frustrating quenched randomness and connectivity on microphase ordering in copolymer melts. Our results show that randomly grafted copol

The morphologies of two series of model graft copolymers were studied using transmission electron microscopy (TEM) and small-angle X-ray scattering (SAXS). Both series of materials have monodisperse polybutadiene (PB) backbones and monodisperse polys

Model multigraft copolymers of butadiene (Bd) and styrene (St) with randomly placed trifunctional, poly(Bd-g-St), and tetrafunctional branch points, poly(Bd-g-St2), were synthesized by hydrosilylation of polybutadiene (∼92 wt % 1,4) with HSiMe2Cl a
