The sample having 10 phr of total CTBN (2.5 phr from ETBN addition and 7.5 phr from the elastomer-modified VER) shows a significant improvement in fatigue behavior over the elastomer-modified vinyl ester resin itself. The higher rubber level of 12.0 phr of total CTBN, 4.5 phr from ETBN and 7.5 phr from the elastomer-modified vinyl ester resin, gives a fatigue resistance that is somewhat similar to that of the elastomer-modified vinyl ester resin itself. [Pg.168]

It is also possible to use DSC to determine the influence that additives have on the curing of polymer products. For example, Karbhari and Kabalnova [93] have investigated the curing kinetics of elastomer-modified, carbon fibre reinforced vinyl ester resins. The influence that the loading of carbon fibre and the percentage of sizing on the fibre have on the cure rate, degree of cure, time to maximum cure and the rate constant were all evaluated. [Pg.243]

Renewed development and marketing effort is expected with brominated epoxy oligomers, now in the hands of Resolution Performance Products, following a sell-off from Shell. These materials are well established for thermosets, such as epoxy resins, phenolics, and vinyl esters, but modified grades have recently been introduced aiming at thermoplastics, such as styrenic and (significantly, because of its potential in electrical and electronics equipment) ABS. Thermoplastic polyesters, elastomers, and polyolefins can also be flame retarded with these materials which have a bromine content of 50-60% weight... [Pg.122]

Elastomer-modified epoxy resins are used in composites and structural adhesives, coatings, and electronic applications. Similar approach to toughen epoxy vinyl esters using other elastomeric materials has been reported (204). Other elastomer-modified epoxies include epoxy-terminated urethane prepolymers, epoxy-terminated polysulfide, epoxy-acrylated urethane, and epoxidized polybutadiene. Preformed dispersions of epoxy-insoluble elastomers have been developed and reported to achieve toughening without Tg reduction (205,206). [Pg.2746]
