ABSTRACT:
This invention relates to radiation curable compositions comprising an alkenyl ether functional polyisobutylene, a cationic photoinitiator, a free radical photoinitiator, and an alkenyl ether compound which is free of isobutylene units. The radiation curable compositions can further comprise an alkylphenol. This invention also relates to hydrocarbon silicone alkenyl ether compounds. The radiation curable compositions exhibit a low cure energy, have a high moisture vapor barrier, high damping characteristics, and a high refractive index, and provide a barrier to corrosive vapors and have maintained or enhanced modulus, tensile strength, and toughness.
