Poly(cyclic conjugated diene) polymers are prepared by polymerizing a cyclic conjugated diene monomer or cyclic conjugated diene monomer and a double bond-containing monomer using a transition metal catalyst, preferably a Ni-based catalyst, in a non-polar solvent containing a basic compound or an aromatic halide solvent. The poly(cyclic conjugated diene) polymer may then be subsequently modified by reaction of at least one of the double bonds of the polymer with a modifying substance, for example hydrogen.

Devulcanized rubber in which sulfuric crosslinking bonds are cut and which contains carbon black particles having very small diameters. Vulcanized rubber of discarded products is devulcanized by heating it at a temperature of 180.degree. C. --350.degree. C. and applying a shearing pressure of 10-150 kg/cm.sup.2 thereto. Reclaimed rubber products are manufactured by vulcanizing and molding, into desired shapes, a material made of only devulcanized rubber in which sulfuric crosslinking bonds are cut and which contains carbon black particles having very small diameters or a material made of the devulcanized rubber mixed with virgin unvulcanized rubber.

The composite clay material is formed of a clay mineral rendered compatible with an organic material through ionic bonding to an organic onium ion having 6 or more carbon number and a main guest molecule having a polar group in its main chain and side chain and molecular length equal to or larger than that of said organic onium ion. The main guest molecule is incorporated at least partially into an interlayer section of the clay mineral which has a hydrogen bonding with the polar group of the main guest molecule. The main guest molecule preferably has a molecular weight ranging from about 100 to 100000. Alternatively a first guest molecule having a polar group and molecular length equal to or smaller than that of the organic onium ion and a second guest molecule having no polar group therein and molecular length larger than that of the organic onium ion are incorporated into the interlayer section of the clay mineral instead of the main guest molecule. The above obtained clay composite material may be mixed with the rubber material.
