Silane terminated prepolymers for adhesives, sealants and coatings are of great industrial importance. They very important because their low toxicity over polyurethanes, silicones, solvent-based products. Hence, many pieces literature which deal with the synthesis, properties applications this polymers hybrid system exist. Silylated polyether (MS polymers) Polyurethane Polymers (SPUR) bases num...

Abstract Dental implants are fixtures that constitute for the replacements of root a missing natural tooth. implant therapy has been widely used restoration partially and fully edentulous patients. The literature emphasizes importance passively fitting prosthesis to prevent prosthodontic complications or even loss fixture integration. Failure achieve force tightening superstructure may result i...

PURPOSE Vinyl polyether silicone (VPES) has a different composition from other elastomeric impression materials as it combines vinyl polysiloxane (VPS) and polyether (PE). Therefore, it is important to study its properties and behavior under different test conditions. This study investigated the dimensional stability of 5 VPES consistencies when stored for up to 2 weeks, with and without using ...

A series of polyether-based diblock copolymers were synthesized by sequential organocatalytic ring-opening polymerization (ROP) either hexene oxide (HO) or octene (OO) as the first monomer with propylene (PO) second monomer. In addition, one triblock terpolymer OO, PO, and styrene (SO) was following same method. The ROP catalyzed triethyl borane (TEB)/(phosphazene base t-BuP2) eicosanol initiat...

Abstract Block copolymers containing polydimethylsiloxane (PDMS) and poly(ethylene oxide) (PEO) or poly(propylene (PPO) with varying molar masses were synthesized in a three-step pathway. The functional homopolymer blocks final diblock characterised using proton Nuclear Magnetic Resonance (1H NMR) Matrix Assisted Laser Desorption/Ionization Time of Flight Mass Spectroscopy (MALDI-ToF-MS). These...

The interaction forces provided by silicone polyether (SPE) surfactants, adsorbed at the interface of octadecyltrichlorosilan monolayer and aqueous surfactant solution, were measured by atomic force microscopy. Changes in the forces in the presence of ethanol were examined for a series of comb-type SPE surfactants. It was found that the steric repulsion provided by the SPE molecules persisted u...
