The prospects for the use of polymer-polymer mixtures based on corn starch as alternative thermoplastic materials to polyolefins are considered. Rheological curves have been obtained, which confirm possibility processing such standard equipment into products. It is shown that content in can reach 90 mass percent. Compared existing biodegradable polymers, plasticized starch-based material no way...

Thermoplastic polymers are currently prepared almost exclusively from fossil feedstocks. In view of the limited availability of such feedstocks, alternative renewable resources are desirable in the long term.[1.2] Polymer production from a renewable resource ideally allows for a complete molecular utilization of the feedstock and carries its molecular structure over into the resulting polymers,...

in this study, the effect of hydrocarbon and rosin ester resins combination on the physical and mechanical properties of thermoplastic road markings were evaluated. at first, two basic thermoplastic road marking formulations based on hydrocarbon and rosin ester resins were prepared. several samples of the blends of two basic formulations for thermoplastic road marking were characterized and com...

Silicone thermoplastic sheeting has been used successfully in the management of hypertrophic and keloid scars resulting from thermal burn injuries. A technique is described that incorporates silicone thermoplastic sheeting for fabrication of a compression face mask. This technique combines the moldability of thermoplastic splinting materials with the therapeutic surface of silicone, yielding th...

We report the synthesis and characterization of a series of multiblock thermoplastic polyurethane hydrogels synthesized with PEG as the soft segment and incorporating an isobutyl-functionalized POSS diol (TMP POSS diol) in the hard segment. The molecular weight of PEG was systematically varied to include 10, 20, and 35 kg/mol, while the molar ratio of POSS diol (as chain extender) to PEG was va...

A commercially available aliphatic thermoplastic polyurethane formulated with a methylene bis(cyclohexyl) diisocyanate hard segment and a poly(tetramethylene oxide) soft segment and chain-extended with 1,4-butanediol was dissolved in dimethylformamide and mixed with dispersed single-walled carbon nanotubes. The properties of composites made with unfunctionalized nanotubes were compared with the...

Nanoimprint lithography technologies (NIL), introduced by Chou et al. in 1995 [1], may be used to overcome the feature size limitation encountered in classical photolithography while remaining more economical than lithographies based on electron, ion beam, x-ray, and scanning probe tips. In the approach involving hot-embossing of a thermoplastic resist layer, a sub-10nm [2] resolution has been ...

Thermoplastic poly(ethylene oxide) (PEO) (Mw(PEO) approximately 4000) has been used to prepare thermosetting nanocomposites incorporating diglycidyl ether of bisphenol A (DGEBA) epoxy oligomer. Blends with various PEO/DGEBA weight ratios were cured using stoichiometric portions of 4,4'-diaminodiphenylmethane. The resulting semi-interpenetrating polymer networks were studied by several technique...
