DIALLYL BISPHENOL

The structure of a soluble prepolyner, resulting from the addition reaction of bisnaleimidodiphenyl methane to diallyl bisphenol A at approximately ISO °C, is confirmed by a detailed high resolution IMR... [Pg.379]

Diallyl bisphenol A, 2, also supplied by Ciba-Geigy, is a commercial grade amber colored viscous liquid at room temperature. Tsrpical hydroxyl content is greater than 0.62eq/100g (0.66eq/100g theoretical). [Pg.380]

A soluble prepolymer results from the addition of bismaleimidodiphenyl methane 1 to diallyl bisphenol A 2 at approximately 150 °C. In the present study, a detailed 13C NMR investigation has provided strong evidence for the proposed structure of the soluble olig< ier. The NMR has also provided s< >e idea of the rate of...

In a similar manner, the hydrosilylation-polymerization of diallyl bisphenol A (278) with 275 in the presence of a platinum catalyst affords polymer 279 that possesses a relatively high glass transition temperature for siloxane polymers (Tg = 28-34 °C) and... [Pg.1764]

The progress of polymerization of Matrimid 5292 can be monitored by Py-GC/MS [19]. The levels of methylphenol, 4-succinimido-4 -aminodiphenylmethane, and 2-(2-propenyl)-4-methylphenol are increased in the pyrolysate as the degree of curing increases. At the same time, the level of 3,3 -diallyl bisphenol A decreases with increasing cure. [Pg.626]

Recently, Boileau et al. [71,72] performed the polyhydrosilylation of diallyl bisphenol A with hydride terminated polydimethylsiloxanes to prepare tailor-made polysiloxanes with anchoring groups composed of dimethyl-siloxane segments (DMS) of different lengths, regularly separated by one bisphenol A (BPA) unit. They studied the influence of the control of the... [Pg.20]

The method for bismaleimide resin filled with whiskers is similar to the preceding. The mass ratio of BMI (bismaleimide) and BA (diallyl bisphenol A) is 1 0.8. First, heat BA to 130°C, then add BMI slowly, prepolymerize for 20 minutes, add the whisker, mix uniformly, pour into a glass mold coated with a release agent, vacuum and deaerate at 120-130°C for 15 minutes, and cure according to the following sequence l45°C/2 h + l60°C/2 h + 180°C/2 h + 200°C/2 h. Finally, posttreat at 220°C for 6 h. [Pg.172]
