Synthesis and characterization of sustainable polyurethane modified by cyclic polysiloxane

In this article, a series of sustainable polyurethanes are prepared by introducing different content of cyclic polysilanol, which may act as a chain extender to replace 1, 4-butanediol (BDO). Consequently, cyclic polysiloxanes are successfully incorporated into the molecular chains to afford organic–inorganic polyurethanes and then their effects on...

Toughening epoxy resin with blocked isocyanate containing soft chain

A series of imidazole (MI) blocked 2,4-toluene diisocyanate (TDI) with polyethylene glycol (PEG-400) as soft segment (PEG-MI-b-TDI) were synthesized for toughening and curing the bisphenol A type epoxy resin (E-44). Fourier transform infrared (FTIR) spectrum indicates that the NCO groups of the isocyanate molecule are blocked with MI. For curing...

Supertoughened Poly(lactic acid)/Polyurethane Blend Material by in Situ Reactive Interfacial...

Poly(lactic acid) (PLA) is well-known as a biocompatible and biodegradable polymer that can be obtained from natural sources. However, the brittleness of PLA is a significant drawback for its wide application. In this study, a poly(lactic acid) (PLA)/polyurethane elastomer prepolymer (PUEP) dynamically vulcanized system was introduced and studied...

Commercially available organosilane (3-glycidoxypropyltrimethoxysilane (GPTMS)) coupling agent was used to treat talc in order to improve the affinity relative between the filler and the polymer in composites as well as filler and polymer in the thermoplastic polyurethane/polypropylene (TPU/PP) blends (talc content was 5 wt%). The talc particles...

Testing Artificial Joints Using Polyurethane Foam

Polyurethane is a polymer that contains a sequence of organic units joined by carbamate or urethane links. Despite the majority of polyurethanes being thermoset polymers which can not be remelted and reformed, there are some which are thermoplastic.Polyurethane polymers are typically formed by a reaction between a poly-isocyanate or di-isocyanate...
