Bicomponent elastomeric fibres |
(57) A coextruded elastomeric fibre comprising:
a) 100 parts by weight of a functionalized selectively hydrogenated block copolymer,
comprising: i) at least two blocks comprising predominantly polymerized monovinyl
aromatic monomer units, ii) at least one block comprising predominantly, before hydrogenation,
polymerized conjugated diolefin monomer units and, iii) on average, in the range of
from 2 to 20 acid or anhydride groups per polymer molecule; and
b) in the range of from 30 to 300 parts by weight of nylon.
