ABSTRACT:
A polymer sheet having enhanced blocking resistance properties comprising a bifunctional surface modifying agent disposed at a surface of the plasticized polyvinyl butyral sheet. The bifunctional surface modifying agent comprises an anti-blocking segment comprising a polyethylene block or a hydrocarbon chain block and a compatibility segment comprising a poly(alkylene glycol) block. A method of manufacturing a polymer sheet having enhanced blocking resistance properties comprises melt processing a polymer into a sheet and disposing a bifunctional surface modifying agent at a surface of the polymer sheet, the bifunctional surface modifying agent comprising a polyethylene block or a hydrocarbon chain block and a poly(alkylene glycol) block. A method of enhancing the blocking resistance of a polymer sheet comprises disposing a bifunctional surface modifying agent at a surface of the polymer sheet, the bifunctional surface modifying agent comprising an anti-blocking segment comprising a polyethylene block or a hydrocarbon chain block and a compatibility segment comprising a poly(alkylene glycol) block.
