An anion exchange membrane is provided by converting carbon-carbon double bonds in the backbone of polystyrene-block-polybutadiene-block-polystyrene (SBS) into epoxide groups. Unmodified SBS is first partially hydrogenated to remove about 65% to about 90% of carbon-carbon double bonds. The remaining double bonds are then converted to epoxide groups to form an epoxidized SBS. UV-initiated ring opening reactions between the epoxidized SBS and haloalkyloxiranes are then employed to simultaneously functionalize and crosslink the epoxidized SBS. The halide groups in the crosslinked polymer network can be replaced via nucleophilic substitution to offer anion conductivity, e.g., via reaction with trimethylamine. Further ion exchange reactions can then be performed to make the membrane hydroxide conductive. The crosslinked membranes described herein exhibit a mechanical strength improvement of 200% compared to unmodified SBS, while maintaining high hydroxide conductivity. This synthetic platform is advantageous to provide mechanically robust anion exchange membranes for fuel cell applications.

The present application provides a resin component, and a prepreg and a circuit material using the same. The resin component comprises unsaturated polyphenylene ether resin, polyolefin resin, terpene resin and an initiator. When the total weight of the unsaturated polyphenylene ether resin, polyolefin resin and terpene resin is defined as 100 parts by weight, the terpene resin is in an amount of 3-40 parts by weight. The polyolefin resin is one or a combination of at least two selected from the group consisting of unsaturated polybutadiene resin, SBS resin and styrene butadiene resin. The present application discloses that the resulting resin composition has good film-forming properties, adhesion and dielectric properties through the coordination of unsaturated polyphenylene ether resin, unsaturated polyphenylene ether resin, polyolefin resin and terpene resin, and the circuit boards using the same have higher interlayer peel strength and lower dielectric loss.
