    摘要： The present invention is directed to a composition for a gel useful in fiber optic cable which has the normal consistency of a grease but which, if desired, will become a rubbery coherent gel upon heating; a method of making the heat-fusible gel, and a method of making a spliceable fiber optic cable, and a fiber optic cable. In the broadest sense, a heat-fusible oil gel composition for fiber optic cable is disclosed, comprising: from 50 to 80 wt. % of a grease-like gel based on a hydrocarbon oil containing from 2 to 10 wt. % of an S-EB or S-EP diblock polymer, or a mixture of these diblock copolymers, and from 20 to 50 wt. % of a grease-like gel based on a polar oil containing from 5 to 25 wt. % of an S-EB-S or S-EP-S triblock copolymer, or a mixture of these triblock copolymers.

    摘要： This disclosure relates to syndiotactic polymers containing units derived from propylene and units derived from C4 to C20 alpha olefins. The polymers can be prepared is slurry or solution polymerization processes using a zirconium-containing metallocene catalyst system. The polymers have a melt flow rate as determined by ASTM D-1238 (230° C., 2.16 kg) of from about 0.1 to about 20 g/10 min. The syndiotactic polymers are useful as viscosity index improvers.
