Crosslinking and Entanglement Effects in Polybutadiene
… and entanglements on segmental motion in polybutadiene. The temperature dependence of T(,1), the spin-lattice relaxation time, T(,2), the spin-spin relaxation time, and T(,1(,(rho))), the spin-lattice relaxation time in the rotating frame are reported for samples of well characterized …

Degradation and stabilisation of diisocyanate cured polybutadiene
Hydroxyl terminated polybutadiene (HTPB) has been used as a rocket propellant binder which is required to be stored for at least twenty years. It is found that the excellent stress-strain characteristics of this propellant can be totally lost, during this long storage, due to the deterioration of …

Stabilisation of isocyanate cross linked polybutadiene binder
Isocyanate cross-linked hydroxy terminated polybutadiene is used as a binder for solid rocket propellant. Rocket motors containing this propellant require a storage life of at least 20 years. During storage it has been found that the important rubbery properties of the binder can be lost due to …

Incorporating Recycled Plastics in Asphalt Binders and Mixtures
… Compatibilizers with polyisoprene (PI) and polybutadiene (PBD) backbones synthesized with polyethylene-block-polyethylene (glycol) (PEPEG) at two different molecular weights were tested. The effect of unreacted Maleic anhydride (MAH) in the compatibilizers was also evaluated.Polyisoprene …

Towards a library of functional block copolymers : synthesis and colloidal properties
… the introduction of diverse functional groups to polybutadiene-containing block copolymers. Various modifications of 1,2-polybutadiene-poly(ethylene oxide) block copolymer precursors are described in detail. Furthermore, extension of the concept to 1,2-polybutadiene-polystyrene block copolymers is …

Functional Triblock Terpolymers for Multicompartment Micelle and Janus Particle Synthesis
… JPs were prepared mainly from polystyrene-block-polybutadiene-block-poly(methyl methacrylate) and polystyrene-block-polybutadiene-block-poly(tert-butyl methacrylate). However, these polymers do not offer many possibilities of chemical alterations and stimuli-responsive elements. Therefore, …
