Abstract
Uses of syndiotactic/atactic block polypropylene are provided in which the molecular weight thereof is preferably at least 120 kD. The syndiotactic/atactic block polypropylene may be used as a polypropylene modifier, a component in an adhesive composition, a shock absorber component, a waterproof membrane component, a packaging film or component thereof, a shapable composition component, and an acoustic absorbent material component, a composition for moulding into a footwear component, a bitumen modifier, a compatibiliser, an emulgator or an emulsifier, as a viscosity improver, and as a spilled oil absorber.
Claims33
