Allyl Glycidyl Ether

Abstract A high grade rubber was made by vulcanizing copolymers of propylene oxide and allyl glycidyl ether. The crude polymer contained both crystalline and amorphous fractions. The total polymer could be sulfur cured without fractionation or removing the catalyst—a partly hydrolized ferric alkoxide, resulting from the reaction of FeCl3 with propylene oxide. Variables in the vulcanization recipe were studied, and a tensile strength of 1980 psi with 560% elongation was obtained. Improved tear and oil resistance were observed as compared with SBR rubber. Other physical properties compared favorably with commencal rubbers, except for compression set.

Abstract The catalyst comprised of triisobutylaluminum, zinc acetylacetonate, and water was used to prepare homopolymer of epichlorohydrin; copolymers of epichlorohydrin with propylene oxide, ethylene oxide, and allyl glycidyl ether; and terpolymers of epichlorohydrin, propylene oxide, and allyl glycidyl ether and of epichlorohydrin, ethylene oxide, and allyl glycidyl ether. The vulcanizates of these rubbers provide variations of stress-strain and dynamic properties, freeze point, hardness, and solvent resistance depending on the type and amount of comonomer. In general, these rubbers have excellent heat, ozone, and oxidation resistance as well as oil and solvent resistance.

Allyl Glycidyl Ether

This paper aims to develop a modified animal glue sand binder for foundry casting with improved water resistance and bonding strength. An efficient method is reported by using sodium hydroxide as the catalyst to improve the operability of animal glue binder and allyl glycidyl ether as the modifier to improve the water resistance and bonding strength. Sand specimens prepared using allyl glycidyl ether-modified animal glue binder were cured by compressed air at room temperature. The proposed method saves energy and is environmentally friendly and inexpensive. Compared with unmodified animal glue binder, standard dog bone sand specimens with allyl glycidyl ether-modified animal glue binder had higher tensile strength of 2.58 MPa, flowability of 1.95 g, better water resistance (a lower decrease in tensile strength at 25 °C and relative humidity of 60%), and good collapsibility. This allyl glycidyl ether-modified animal glue binder is suitable for practical application in the foundry industry.
