Publication number: 20120083568Abstract: A series of low, medium, and high molecular weight copolymers containing methyl methacrylate, n-butyl acrylate. 2-hydroxyethyl methacrylate, and 2,2,2-trifluoroethyl methacrylate were synthesized by solution polymerization under monomer-starved conditions. The copolymers were crosslinked with a methylated melamine formaldehyde resin in order to obtain thermosetting acrylics. Lower wettability, higher oxygen permeability, and lower refractive index were observed for higher concentrations of fluorinated monomer in the copolymer composition and high number-average hydroxyl functionality of the high molecular weight copolymers increased the crosslink density of the acrylic films, thereby resulting in improved tensile strength and tensile modulus.Type: ApplicationFiled: February 3, 2011Publication date: April 5, 2012Applicants: Toyota Motor Engineering & Manufacturing North America, Inc., University of Akron, Toyota Motor CorporationInventors: Mark D. Soucek, Cynthia G. Templeman, Elif Alyamac, Masahiko Ishii

Publication number: 20120083551Abstract: Telechelic resins with reactive end groups (e.g., epoxy phosphate and epoxy ester) were synthesized using bisphenol-A (BPA) epoxide. The bisphenol-A based epoxide and the telechelic resins were all modified with tetraethylorthosilicate (TEOS) oligomers to produce epoxide/polysilicate (organic/inorganic) hybrid systems. The modified epoxides were thermally cured with a melamine-formaldehyde resin, cast on steel substrates and salt spray analysis revealed that the inorganically modified epoxides provided improvement over unmodified epoxide resins with respect to both corrosion resistance and adhesion to steel substrates.Type: ApplicationFiled: February 3, 2011Publication date: April 5, 2012Applicants: Toyota Motor Engineering & Manufacturing North America, Inc., Toyota Motor Corporation, University of AkronInventors: Mark D.
