| titleOfInvention | Tension setting polymer alloy compositions |
| abstract | The invention provides a tension setting polymer alloy which is a homogeneous multiphase blend containing a thermoplastic polymer and an elastomeric polymer. A preferred tension setting polymer alloy is one wherein the Residual Deformation (RD) of the polymer alloy in a Dome Expansion Test is at least 50%, the Dome Expansion test being a test in which: <SL> <LI>(a) a circular plaque of polymer is secured over the open end of a cylindrical pressure vessel, and an annular spacer and pressure plate is mounted above the plaque to define an expansion chamber; <LI>(b) the plaque is subjected to pressure from within the pressure vessel such that it deforms outwardly and into contact with the pressure plate which limits its axial expansion to 30%; <LI>(c) pressure is applied from within the pressure vessel until the plaque has expanded to fill the expansion chamber, whereupon the pressure is released; <LI>(d) the plaque is allowed to recover; and <LI>(e) the extent of the residual deformation (as defined by the axial displacement of the centre of the plaque) after recovery is measured and compared to the maximum deformation; </SL> wherein the RD value is defined as the ratio of the axial displacement of the centre of the plaque after release of pressure and recovery, to the maximum axial displacement of the centre of the plaque, expressed as a percentage. The blends are particularly useful as liners for pipelines. Suitable elastomers are SBS, and SEBS, and suitable thermoplastics are homo and co-polymers of ethylene, propylene and butylene. |
