Patent number: 10364345Abstract: An monolithic interlayer with high stiffness and when laminated into a glass panel, the glass panel exhibits good clarity, while maintaining the processability of a polyvinyl acetal, such as polyvinyl butyral resin used to make the monolithic interlayer. The monolithic interlayer comprising a polymer blend of: (A) polyvinyl acetal (e.g. PVB); and (B) one or more cellulose esters. The polymer blend increases the structural strength to the monolithic interlayer by increasing the E? modulus of the monolithic interlayer while optionally maintaining good optical clarity.Type: GrantFiled: December 3, 2015Date of Patent: July 30, 2019Assignee: Solutia Inc.Inventors: Aristotelis Karagiannis, Bruce Edward Wade, Khanh D.

Publication number: 20190016097Abstract: A polyvinyl acetal poly(vinyl acetal), such as polyvinyl butyral, resin formulation, a method of extruding poly(vinyl acetal) resins, and related materials and products that provide for monolithic poly(vinyl acetal) sheets and glass panes having high Tg of at least 50° C. and high modulus at acceptable rates as indicated by their high melt flow index. This is made possible by a reduction in the amount of plasticizer while using a low molecular weight resin not to exceed 160,000 to obtain a thermoplastic resin having a high melt flow index and high Tg. The articles made with these monolithic interlayer sheets can be used in applications that require good modulus at outdoor temperatures.Type: ApplicationFiled: September 18, 2018Publication date: January 17, 2019Applicant: Solutia Inc.Inventors: Aristotelis Karagiannis, Megan L.
