A polymerizable composition comprises an alpha-olefin hydrocarbon monomer, an effective amount of an organometallic catalyst of a Group VIII metal, preferably Ni or Pd, and at least one of water and air. Novel catalysts for polymerizing alpha-olefin hydrocarbon monomers provide improved processes and products. Methods of the invention include polymerizing the composition in open air and in the presence of water to provide novel polymers.

La présente invention concerne une composition polymérisable comprenant un monomère d'hydrocarbure d'alphaoléfine, une quantité efficace d'un catalyseur organométallique ayant pour base un métal du groupe VIII, de préférence Ni ou Pd, et de l'eau, ou de l'air, ou les deux. Des catalyseurs nouveaux pour la polymérisation de monomères d'hydrocarbures d'alphaoléfines permettent d'améliorer les procédés et les produits obtenus. Les procédés selon l'invention consistent à polymériser la composition en plein air et en présence d'eau, afin d'obtenir des polymères nouveaux.
