Zinc dimethacrylate

The free radical polymerization was initiated at 131°C using styrene and LUPERSOL 233 (170 ppm). This mixture was then treated incrementally with sufficient amounts of zinc dimethacrylate dissolved in styrene monomer to prepared copolymers having a zinc diacrylate contents of 400 ppm, 600 ppm, and 800 ppm. The results of copolymer physical testing of these experimental agents is provided in Table 1. [Pg.699]

Relevant systems are mbber-toughened epoxy resins, high-impact acrylic (PMMA particles in mbber matrix, obtained by radical polymerization of 80/20 MMA/EVAc mixture), polyimide/silica hybrid materials (obtained using the sol-gel method), and a very high strength ( 60 MPa) mbbers (obtained by peroxide cure of a hydrogenated nitrile rubber/ zinc dimethacrylate system) [Inoue, 1995]. [Pg.564]

In a patent issued to the US Army in the late 1980s, the zinc salts of acrylic acid and methacrylic acid were used to upgrade the properties of hydrogenated nitrile rubber (HNBR) [3]. The goal of this work was to develop abrasion-resistant materials that could be used to extend the service life of tank treads. Zinc dimethacrylate (ZDMA) proved to be the best material in the study for improving the tear strength, abrasion resistance, and high temperature performance of HNBR. [Pg.214]

Saret 633 and Saret 634 (Sartomer Company) are the scorch-retarded versions of zinc diacrylate and zinc dimethacrylate, respectively. The Saret metallic coagents are used in rubber compounding to avoid premature curing during mixing. [Pg.226]

Solid monomer-solid initiator systems were tried with a variety of monomers and initiators. Two types of monomer systems were used 1) monomers whose melting points were lower than the adiabatic reaction temperature. Acrylamide worked well but n-octadecyl acrylate did not because it was not sufficiently reactive 2) High melting point monomers with a reactive diluent in which the monomer could dissolve at high temperature. Zinc dimethacrylate/acrylamide or zinc dimethacrylate/methacrylic acid both supported frontal propagation with BPO initiator. [Pg.228]

To achieve reproducible front velocities a mold was made, and a four-ton hydraulic press was used to pack the mixture. The resulting pellet was then sanded down to fit into a 16 x 150 mm test tube. The sanding of the pellets had no effect on the green density which was to be determined later. Unfortunately, zinc dimethacrylate adhered to the mold. Acrylamide was used then as the sole monomer. [Pg.228]

Sartomer s Saret zinc diacrylate and zinc dimethacrylate coagents were evaluated in the peroxide vulcanisation of EPDM automotive belt and hose compounds. Cure characteristics and effects on mechanical properties, heat and water resistance and adhesion of EPDM to metal and synthetic fibre reinforcements and to other mbbers were investigated. The results of this study and other experiments with Saret coagents in rabber formulations are discussed. 6 refs. [Pg.81]
