ABSTRACT:
A composition to be used for the manufacture of fibers, filaments, melt blown or spun bond non-wovens or cast or blown films, comprising at least 50 wt % of a styrenic block copolymer; a polyolefin in an amount of from 10 to 30 wt %; a resin which is compatible with the poly(styrene) blocks in the styrenic block copolymer in an amount of at least 5 wt %, and a resin which is compatible with the hydrogenated polybutadiene blocks in the styrenic block copolymer an amount of at least 3 wt %, wherein all weight percentages are relative to the weight of the complete composition; styrenic block copolymers to be used therein; and fibers, melt blown or spun bond non-wovens or cast or blown films prepared from it.
