Title: The Innovative Contributions of Barney Vallino, Jr.

Introduction

Barney Vallino, Jr. is a notable inventor based in Homewood, IL (US). He has made significant contributions to the field of polymer chemistry, particularly in the development of methods for preparing and concentrating latex polymers. With a total of 2 patents to his name, Vallino's work has implications for various industrial applications.

Latest Patents

Vallino's latest patents include a "Method for the preparation of dried latex polymer from aqueous emulsion." This innovative method involves forming a polymeric latex or water-in-oil emulsion and partially inverting the latex by regulated contact time with water. The process is designed to occur within a time span of 0.5 to 10.0 seconds, with a preference for less than 1 second. A preferred operation is carried out in a static mixer, where the contact time for inversion is regulated by the diameter or length of a cylindrical tube containing static baffles.

Another significant patent is the "Method for the concentration of water-in-oil emulsions of water soluble." This method focuses on the concentration of water-in-oil emulsions of water-soluble vinyl addition polymers. The process involves distilling the emulsion under a vacuum while maintaining the water-oil phase ratio substantially equal to the starting latex. This careful maintenance allows latices to be concentrated to as high as 70% by weight polymer.
