Patent number: 6890969Abstract: This invention is directed to a method of preserving colloid-stabilized polymer emulsions against microbial attack and spoilage using selected cationic compounds. It is also directed to compositions containing colloid-stabilized polymer emulsions and cationic compounds that are resistant to contamination with biodeteriogenic microbes. It has been discovered that specific cationic compounds are particularly effective against biodeteriogenic microbes in preserving polymer emulsions that have been stabilized with protective colloids, such as poly(vinyl alcohol). Examples of suitable microbicidal cationic compounds are: substituted pyridinium salts, substituted guanidine salts, tetrasubstituted ammonium salts, and polymeric cationic compounds.Type: GrantFiled: November 29, 2001Date of Patent: May 10, 2005Assignee: Air Products Polymers, L.P.Inventors: John Joseph Rabasco, Dennis Sagl

Patent number: 6689829Abstract: Hydroxyalkylamines can, in addition to imparting antistatic properties, significantly improve the color, i.e., the whiteness, of polyolefin resins produced with chromium-based catalysts and metallocene catalysts. Additionally, such compounds can impart improved whiteness at a loading significantly lower than that required to impart antistatic properties. Surprisingly, the discovered improvement in whiteness is not, however, observed in resins produced using other types of catalysts.Type: GrantFiled: January 21, 2003Date of Patent: February 10, 2004Assignee: Phillips Petroleum CompanyInventor: Mark K.
