Latest Patents

Holder's recent patents showcase his expertise in developing advanced materials. One of his latest inventions involves "Reinforced plastic compositions containing graft copolymers." This patent discusses the creation of acrylate graft copolymers using a two-stage process that begins with the reaction of a backbone polymer, such as 1,2-polybutadiene or an ethylene/propylene/alkylidene norbornene terpolymer. The innovative approach employs a mixture of dinitrogen tetroxide and oxygen to generate a nitrooxidized polymer. This polymer integrates nitro and peroxy nitrate functions, which act as sites for the subsequent graft polymerization of an acrylate monomer. The resulting graft copolymers consist of 5 to 80 weight percent of the backbone polymer, with the remainder derived from the acrylate monomer.

Another notable patent by Holder is "Graft copolymer coated reinforcing agents," which applies a similar innovative process to create acrylate graft copolymers, emphasizing their potential for reinforcing various materials.
