摘要： The present invention is based upon the unexpected finding that polyisoprene rubber which is clear and of high purity can be cured utilizing the curative system of this invention to attain an elongation at break of greater than 1200% without compromising the clarity or purity of the rubber. The curative system of this invention is comprised of a carbonyl inhibited platinum catalyst, and a branched crosslinking agent having at least 2 hydrosilyl groups per molecule. The curative system of this invention can be used to cure solid polyisoprene rubber that is used in a wide variety of application and is a particular value in curing polyisoprene rubber used in manufacturing sporting goods, healthcare, and medical products. The present invention more specifically discloses a curable polyisoprene rubber composition comprising: (1) a polyisoprene rubber comprised of repeat units that are derived from isoprene monomer, (2) a carbonyl inhibited platinum catalyst, and (3) a crosslinking agent having at least 2 hydrosilyl groups per molecule.
