    Abstract: Elastomeric conjugated diene polymer structures are produced by cross-linking mixtures of conjugated diene polymers and oily unbranched polybutadienes. Specified diene polymers are polyisoprene, butadiene-acrylonitrile copolymers, polybutadienes and, especially, copolymers of butadiene and styrene. The low molecular weight polybutadiene may be present in amount from 10 to 80% based on the diene polymer. The cross-linking may take place at 120 to 150 DEG C. in the presence of the usual vulcanization acids and accelerators.

    Abstract: A fertilizer is rendered non-dusting and non-caking by coating with 0.01-0.6% of an isomerized drying polyene polymer. The polymer may be obtained from isoprene, piperylene, cyclopentadiene, cyclohexadiene-1,3, butadiene, 3 - methylheptatriene - 1,4,6, or n - decatriene-1, 5,9. It may be copolymerized with up to 50% of ethylene, propylene, butylene, isobutylene, vinyl-acetylene, styrene, a -methylstyrene, or acrylonitrile. It may also contain up to 50% of a polymer which is incapable of further polymerization, e.g. polystyrene or polyacrylonitrile. It may have a molecular weight of 500-40,000. Isomerization may be effected before, during or after coating. The fertilizer may contain ammonium, potassium, calcium, copper, manganese, zinc, phosphate, nitrate, chloride, sulphate, carbonate, or urea. It may be in granules having a diameter of 2-4 mm.
