Polymer sheet comprising a fatty acid amide as an antiblock additive

摘要

Disclosed is a plasticized polyvinyl butyral sheet comprising a fatty acid amide having the formula R-CO-NH-R', wherein R defines an anti-blocking segment comprising a hydrocarbon chain having 12 to 40 carbon atoms and R' defines H or a hydrocarbon chain having 1 to 40 carbon atoms. Also disclosed is a method of manufacturing a polymer sheet comprising incorporating a fatty acid amide having the formula R-CO-NH-R', wherein R defines an anti-blocking segment comprising a hydrocarbon chain having 12 to 40 carbon atoms, and R' defines H or a hydrocarbon chain having 1 to 40 atoms with the polymer to impart anti-blocking properties to a surface of said polymer sheet, wherein said polymer is plasticized polyvinyl butyral.
