A method of making a coated film comprises coating a first side of a base film with a coating material to form the coated film; wherein the base film was formed in a calendaring process, and wherein, during the calendaring process, the first side physically contacted less surface area of a first roll than a second side physically contacted of a second roll at a given time; and wherein the coated film has an uncoated second side.

In one embodiment, a brightness enhancement film comprises: a diffusing film comprising a front surface and a back surface, a coating on the front surface, and light redirecting structures disposed in the coating. The brightness enhancement film is capable of collimating light, and wherein, without the coating, the diffusing film would be capable of spread light passing through the back surface. In another embodiment, the brightness enhancement film comprises: a diffusing film comprising a front surface and a back surface, a coating on the front surface, and light redirecting structures disposed in the coating. The diffusing film has a stress retardation gradient of less than or equal to 50 nm/in, wherein an interval for calculation of the stress retardation gradient is less than 1 inch. The brightness enhancement film is capable of collimating light.

A process for the production of a bisphenol comprises reacting a feed comprising a phenol, a ketone and water in the presence of an ion exchange resin catalyst to produce an effluent; determining the para&#x2014;para bisphenol selectivity of the reaction; and adjusting the concentration of the water in the feed based upon the para&#x2014;para bisphenol selectivity in the effluent.

Process for the synthesis of bisphenol

A commercial scale continuous process for the production of a bisphenol comprising reacting a phenol and a ketone in the presence of a modified ion exchange resin catalyst, wherein said modified ion exchange resin comprises a crosslinked gellular acid functionalized polystyrene resin modified by neutralization of with a mercapto promoter.

A method for producing bisphenol includes introducing a phenol and a ketone into a fixed, supported catalytic bed reactor system in a downflow mode, reacting the phenol and the ketone to form a reaction mixture, and recovering the bisphenol isomer from the reaction mixture. The preferred bisphenol isomer is bisphenol A, or p,p'-bisphenol A, produced from the reaction of phenol and acetone. The reactor for producing the bisphenol A from the reaction of phenol and acetone includes an ion exchange resin catalyst disposed in a bed and packing randomly distributed throughout the ion exchange resin catalyst to improve heat transfer efficiency and reduce compression of the catalyst bed.
