The ionizing radiation can cause bonding between polymeric additive components and create a polymer matrix within the sealant composition that increases the mechanical strength of the sealant composition.Type: GrantFiled: August 25, 2009Date of Patent: April 24, 2012Assignee: Halliburton Energy Services Inc.Inventors: Samuel J. Lewis, David F. Myers, James Lynn Davis, Vikram Rao, Vijay Gupta, Lynn Margaret Soby, Andrew K. Dummer

STYRENE-BUTADIENE BASED REDISPERSIBLE POLYMER POWDERS WITH IMPROVED STABILITY IN CEMENT APPLICATIONS
Publication number: 20120077907Abstract: A water redispersible polymer powder is produced by drying an aqueous mixture of a carboxylated styrene butadiene polymer and a colloidal stabilizer which includes a polyvinyl alcohol modified with an alkyl end chain. The alkyl modified polyvinyl alcohol provides excellent redispersibility of the redispersible polymer powder without adversely affecting spray drying. Cement compositions such as mortars, which contain the redispersible polymer powder with the alkyl modified polyvinyl alcohol exhibit unexpectedly superior stability and an unexpectedly lower rate of mortar viscosity buildup which is advantageous for workability or troweling.Type: ApplicationFiled: September 21, 2011Publication date: March 29, 2012Inventors: Etienne Lazarus, Gerold Lohmüller, Juergen Dombrowski, Hartmut Kuehn, Margarita Perello, Sonja Scharlemann
