Abstract

Vinyl cyclohexane polymers of molecular weights from 10,000 to 2,000,000 are produced by hydrogenating in the liquid phase with hydrogen a homopolymer, copolymer or graft polymer of styrene or a mixture of polymers containing polystyrene of molecular weights from 10,000 to 2,000,000 at 50 DEG -270 DEG C. and a pressure of 10-1,000 atmospheres in the presence of a supported catalyst containing 0,01-95% of a Group VIII metal with an atomic weight exceeding 58, e.g. Ni, Co, Ru, Rh, Pd or Pt. The polystyrene may be prepared by thermal or ionic polymerization of styrene, e.g. in emulsion or suspension. Copolymers may contain butadiene, isobutylene, vinyl toluene, a methylstyrene, divinylbenzenes, ethylene, propylene, acrylic or methacrylic esters, vinyl esters or ethers, acrylonitrile, methacrylonitrile, N-vinylcarbazole and/or mixtures. Hydrogenation is carried out using a melt or solution of the polymer, e.g. 5-25%, with hydrocarbons and/or saturated ethers or alcohols, e.g. cyclohexane, tetrahydrofurane, benzene. Carriers for the catalyst may be porous substances, e.g. C, Al2O3, pumice, kieselguhr, silica gel, and promoters, e.g. Cr, Cu, Mn or cerium oxide, may be used for Ni and Co catalysts. The process may be continuous, e.g. using a suspended catalyst which may be recycled. The vinyl cyclohexane may be pressed into sheets or moulded.
