BPA/DC-BMI prepolymer

Epoxynovolak resin and BPA/DC-BMI prepolymer, tert.butyl peroxide and Zn acetate [106, 107] or 2-phenylimidazole and other catalysts [108] were filled with wollastonite. Carbon-fiber reinforced composites were obtained using a binder, which consisted of BPA/DC, BMI, an epoxynovolak, 2-ethyl-4-methylimidazole and an organic solvent [109]. A BPA/DC-BMI prepolymer in methylethylketone was mixed with middle-molecular-weight epoxide resin (Epikote 1001), 2-ethyl-4-methyl-imidazole, Zn acetate and triethylenediamine thermal shock resistant GRP was thus obtained [110].

As in the cyanate/epoxide compositions, polysulfone is used as an additive in cyanate/epoxide/maleimide systems. As an example, a composition for carbon-fiber composites should be mentioned. It contains BPA/DC-BMI prepolymer, epoxide resin and polyethersulfone [111-113] Zn acetate and dicumyl peroxide are added. Polyethersulfone powder was added to the three-component system with 4,4 -diamino-diphenylmethane-based tetraepoxide as one of the epoxy resins used [114]. [Pg.54]

A coating composition consists of BPA/DC-BMI prepolymer, epoxide resin and Zn acetate in dimethylformamide a solution of polyhydantoin in CH2C12 is added [121]. [Pg.55]

An electroinsulating coating was obtained by mixing a polyimide resin with BPA/ DC or BPA/DC-BMI prepolymer. The low-molecular-weight polyimide resin contained reactive end groups (—C = CH, COOH, —NH2 etc.) [140]. [Pg.57]
