Publication number: 20150073111Abstract: This invention pertains to fluoroelastomers comprising copolymerized units of vinylidene fluoride, at least one other fluoroolefin and a cure site monomer having a secondary cyano group, as well as cured fluoroelastomer compositions made therefrom. It has been surprisingly discovered that fluoroelastomers that contain a cure site monomer having a secondary cyano group contain much less gel than do similar fluoroelastomers that employ a cure site monomer having a primary cyano group. Furthermore cured (i.e. crosslinked) fluoroelastomer compositions that contain a fluoroelastomer having secondary cyano groups have a better (i.e. lower) compression set than do similar cured fluoroelastomer compositions that contain a fluoroelastomer having primary cyano groups.Type: ApplicationFiled: September 3, 2014Publication date: March 12, 2015Inventors: Ming Hong Hung, Phan Linh Tang
