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 …

Polymeric Nanoparticles for the Modification of Polyurethane Coatings
… chip resistance. Various narrowly distributed polybutadiene-b-poly(methyl methacrylate) (B-M) block copolymers differing in composition and molecular weights were synthesized and studied with respect to their self-assembly in organic selective solvents. Dynamic light scattering and transmission …

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, …

Structural analysis of nanoparticles by small angle X-ray scattering
… complexes and hamburgers of semi-crystalline polybutadiene/polyethylene nanoparticles. The study of the calcium-phosphate-protein complexes consisted in looking for the influence of a protein, Fetuin-A, also called ahsg, onto the calci_cation at early stage. For the purpose, calcium and …

The Studies of Polymer Adhesion Using Segmental Dynamics Model
… techniques. The method was first applied to bulk polybutadiene, and the model was found to describe the density, bulk modulus, and cohesive energy fairly well. The model was further verified by investigating the structure and dynamics of bulk polybutadiene. Also, the effects of high density and …
