Patent number: 9957358Abstract: Curable silsesquioxane polymers are described comprising a core comprising a first silsesquioxane polymer and an outer layer comprising a second silsesquioxane polymer bonded to the core. The silsesquioxane polymer of the core, outer layer, or combination thereof comprises reactive groups that are not ethylenically unsaturated groups. The first silsesquioxane polymer of the core is bonded to the second silsesquioxane polymer of the outer layer via silicon atoms bonded to three oxygen atoms. In some embodiments, the outer layer has a higher concentration of reactive groups than the core. In this embodiment, the core may be substantially free of reactive groups. In other embodiments, the core has a higher concentration of reactive groups than the core. In this embodiment, the outer layer may be substantially free of reactive groups. The core and outer layer each comprise a three-dimensional branched network of a different silsesquioxane polymer.Type: GrantFiled: September 16, 2015Date of Patent: May 1, 2018Assignee: 3M Innovative Properties CompanyInventor: Jitendra Rathore

Patent number: 9957360Abstract: A composition and a method are provided for graphene reinforced polyethylene terephthalate (PET). Graphene nanoplatelets (GNPs) comprising multi-layer graphene are used to reinforce PET, thereby improving the properties of PET for various new applications. Master-batches comprising polyethylene terephthalate with dispersed graphene nanoplatelets are obtained by way of compounding. The master-batches are used to form PET-GNP nanocomposites at weight fractions ranging between 0.5% and 15%. In some embodiments, PET and GNPs are melt compounded by way of twin-screw extrusion. In some embodiments, ultrasound is coupled with a twin-screw extruder so as to assist with melt compounding. In some embodiments, the PET-GNP nanocomposites are prepared by way of high-speed injection molding. The PET-GNP nanocomposites are compared by way of their mechanical, thermal, and rheological properties so as to contrast different compounding processes.Type: GrantFiled: March 17, 2016Date of Patent: May 1, 2018Assignee: Niagara Bottling, LLCInventors: Jay Clarke Hanan, Sudheer Bandla
