Glycols in polyurethane foam formulations with a starch-oil composite

Autor: K. Eskins, R. L. Cunningham, Frederick C. Felker, Sherald H. Gordon

Publikováno v: Journal of Applied Polymer Science. 69:957-964

A dry starch-oil composite was blended with each of three glycols; ethylene, polyethylene, and propylene, and then reacted with isocyanate to produce polyurethane foams. The liquid glycols permitted the dry composite to blend well with the other ingr

Jet-cooked starch-oil composite in polyurethane foams

Autor: Frederick C. Felker, K. Eskins, R. L. Cunningham, Sherald H. Gordon

Publikováno v: Journal of Applied Polymer Science. 64:1355-1361

A new jet-cooked starch-oil composite has been blended with a polyester polyol and then reacted with isocyanate to give a polyurethane foam. Infrared spectroscopy and microscopy have been used to examine the resultant products. Infrared spectra have

Effect of processing conditions on intrinsic viscosity of extruded cornstarch

Autor: R. L. Cunningham

Publikováno v: Journal of Applied Polymer Science. 60:181-186

Unmodified cornstarch from dent corn was used in this study to determine the effect of twin-screw extrusion conditions on the intrinsic viscosity of this polysaccharide and water. The study focused on the intrinsic viscosity of the cornstarch as a fu

Hydrophilic foams containing corn products for horticultural use

Autor: Sherald H. Gordon, Richard V. Greene, E. B. Bagley, M. E. Carr, R. L. Cunningham

Publikováno v: Journal of Applied Polymer Science. 51:1311-1317

Polyurethane foams containing equal amounts of commercial unmodified cornstarch and a polyisocyanate-terminated polyether exhibit properties suitable for horticultural applications. The use of cornstarch in the foam formulation increased the volume b

Preparation and properties of rigid polyurethane foams containing modified cornstarches

Autor: M. E. Carr, E. B. Bagley, R. L. Cunningham

Publikováno v: Journal of Applied Polymer Science. 44:1477-1483

Rigid polyurethane foams were prepared containing 20% (based on weight of polyol) unmodfied or modified cornstarches. The cornstarches had been modified by breeding or conversion methods and included waxy, acid-modified waxy, malto-dextrin, and canar

Modifications of Urethane-Foam Formulations UsingZea mays Carbohydrates

Autor: E. B. Bagley, T. C. Nelsen, M. E. Carr, R. L. Cunningham

Publikováno v: Starch - Stärke. 44:141-145

Four carbohydrates derived from Zea mays (corn), ordinary cornstarch, two high-amylose starches (one instant starch), and canary dextrin, were substituted partially (8–30%) for polyether polyol in rigid polyurethane foams. Because of different carb
