| titleOfInvention | Modifiers for Thermoplastic Alloys and Alloys Produced Using Such Modifiers |
| abstract | The invention relates to non cross-linked modifiers for thermoplastic alloys comprising from 20 to 80% by weight based on the modifier of an interpolymer of ethylene and an alpha-olefin having from 4 to 12 carbon atoms grafted with an acid functionality, preferably maleic anhydride, having a Melt Index of from 0.3 to 100 and a density of 0.85 to 0.91 prior to being grafted and from 80 to 20% by weight of an ungrafted diene containing interpolymer derived from ethylene and an alpha-olefin having from 3 to 12 carbon atoms and an amount of a cross-linking component effective to provide cross-linking during subsequent melt blending with a condensation polymer having a melting point of at least 150° C. The modifier permits the making of thermoplastic alloys using the modifier by the steps of: A) melt blending the modifier with up to 50% by weight based on the total content of polymeric components in the alloy of a condensation polymer having polar groups under conditions such that the curative action of the cross-linking component is triggered and a phase inversion occurs in which the condensation polymer becomes the matrix component; and B) recovering the resulting thermoplastic alloy. The invention also relates to thermoplastic alloys comprising: a) from 20 to 60 wt % of the total polymer weight of polymer of a condensation polymer having polar groups; and b) up to 80 wt % of a crosslinked dispersed elastomeric modifier comprising from 20 to 80% by weight based on the modifier of a interpolymer grafted with acid functionality, preferably maleic anhydride, of ethylene and an alpha-olefin having from 4 to 12 carbon atoms having a Melt Index of from 0.3 to 100 and a density of 0.85 to 0.91 prior to being grafted and from 80 to 20% by weight of an ungrafted diene containing interpolymer derived from ethylene and an alpha-olefin having from 3 to 12 carbon atoms; said composition having a flexural modulus of from 100 MPa to 700 MPa. |
