Vanderbilt process

The Vanderbilt process involves the mechanical frothing of air into a plastisol containing proprietary surfactants by means of an Oakes foamer or a Hobart-type batch whip. The resulting stable froth is spread or molded in its final form, then gelled and fused under controlled heat. The fused product is open-ceUed with fine cell size and density as low as 160 kg/m (10 lbs/fT). 

Starch can be enzymically converted in the presence of pigment. The conversion follows a similar time-temperature cycle as in neat starch conversion. The pigment will adsorb a portion of the enzyme adsorption can be minimized by the addition of sodium silicate to the mixture prior to the addition of the enzyme (Vanderbilt process). Even with silicate treatment, a higher quantity of enzyme will be required to reach a specific viscosity target. Other coating components, such as latex and lubricants, have to be added after the conversion. The Vanderbilt process is now rarely used for the preparation of coating binder. 

Figure 6.1 Attack of the proplyds A Hubble Space Telescope close-up of the Orion Nebula reveals disks of dust and gas surrounding newly formed stars. These fuzzy blobs, called proplyds, may be infant solar systems in the process of formation. This chunk of the sky spans about 0.14 light-years.

In 1963 he became professor of physiology at Vanderbilt University in Nashville, Tennessee. He was awarded the Nobel Prize for physiology or medicine in 1971 for isolation of cyclic adenosine monophosphate (cyclic AMP) and for demonstrating its involvement in numerous animal metabolic processes. From 1973 until his death he was a member of the faculty of the University of Miami Medical School.
