1. A melt extrudable, moisture curable, thermoplastic polymer fiber comprising an elastomeric styrenic block co-polymer which has been modified prior to fiberization by thoroughly mixing with and grafting onto said copolymer a silane or mixtures of silanes having the formula;

  • ##STR2## wherein;

    Z is selected from the group consisting of double bonded groups capable of reaction under radical polymerization conditions;

    R1, R2, and R3 are selected from the group consisting of alkoxy, Cl, Br, ester, O--Si, alkyl and aryl groups, provided, however, that at least one R group must be reactive in order to function as a hydrolytically reactive agent;

    and wherein said silane has been added to said elastomeric polymer in an amount between about 0.01 and about 10 weight percent.
