Notes:
Allyl glycidyl ether and maleic anhydride, mixed in equimolar quantities, cure together readily in the presence of air, peroxide, and/or Lewis acids. Outstanding properties of the castings formed are hardness (Barcol 50-60 at 25°C., 30 at 150°C.), clarity and heat distortion temperature (165-168°C.). Color is yellow to amber, and strength properties are adequate. Water resistance is fair. The mixture is too thin for convenient use in laminating, but it can be bodied by heating (1 hr., 110°C.), giving a syrup of 50 cpoise. In glass cloth laminates, through-cure appears to be inhibited by the glass. The addition of styrene overcomes this effect. Small amounts are best (5-20%), since large quantities impair elevated temperature strength. Unusually good strength is attained even at 500°F., but resistance to aging at 500°F. is poor.
