Abstract
Novel compositions comprising polystyrene-polydiene-polystyrene block copolymers and an amount of a halogenated polyolefin effective to provide improved resistance to solvents or oils. The compositions are particularly useful for preparing footwear tread members.
Claims17
A composition comprising a thermoplastic, elastomeric block copolymer(s) of a polystyrene--polyisoprene--polystyrene and/or a polystyrene--polybutadiene--polystyrene in an amount between about 20% to about 95% by weight of the composition;
- a halogenated polyethylene polymer having a halogen content between about 5% to about 50% by weight and the halogenated polyethylene polymer is present in an amount between about 1% to about 35% by weight of the composition;
- an extender oil or plasticizer in an amount between 0% to about 50% by weight of the composition and, a polystyrene material in an amount between 0% to about 15% by weight of the composition.
A composition comprising a thermoplastic, elastomeric block copolymer(s) of a polystyrene--polyisoprene--polystyrene and/or a polystyrene--polybutadiene--polystyrene in an amount between about 20% to about 95% by weight of the composition;
- a chlorinated polyethylene polymer having a chlorine content between about 5% to about 50% by weight and the chlorinated polyethylene polymer is present in an amount between about 1% to about 35% by weight of the composition;
- an extender oil or plasticizer in an amount between 0% to about 50% by weight of the composition and, a polystyrene material in an amount between 0% to about 15% by weight of the composition.
