Abstract: Thermoplastic silicone elastomer compositions are disclosed. The thermoplastic elastomer compositions comprise a blend of an organic thermoplastic elastomer and a silicone composition. A process for forming a vulcanised thermoplastic elastomer composition is also disclosed. The thermoplastic elastomer compositions can be used to form functional and/or aesthetic automotive parts such as gear knobs, seat belt connectors, interior mats, airbag protective covers, and over-moulded skins for dash boards and armrests; to form appliance parts; to form soft-feel grips for hand held devices; and to form medical devices, sporting goods and general rubber parts. The thermoplastic elastomer compositions provide durable aesthetics, haptic and ergonomic properties along with stability to most commonly used chemicals and high mechanical performance, abrasion and scratch resistance.

Abstract: A process for increasing the scratch resistance of a composition comprising a thermoplastic organic polymer and a scratch resistant polymer composition per se. The process for increasing the scratch resistance of a composition comprising a thermoplastic organic polymer (P) comprises reactively mixing a thermoplastic organic polymer (A) and an organopolysiloxane (B) in a first step (I) at a temperature at which the thermoplastic organic polymer (A) and the organopolysiloxane (B) are in liquid phases to form a masterbatch. The organopolysiloxane (B) contains at least one functionality capable of reacting with the thermoplastic organic polymer (A) so that a copolymer of components (A) and (B) is formed in the masterbatch during the reactive mixing. The process further comprises a second step (II) of mixing the masterbatch with the composition comprising the thermoplastic organic polymer (P).

Abstract: A process for the production of a polymer composition is disclosed. The polymer composition comprises an organopolysiloxane dispersed in a thermoplastic organic polymer liable to thermo-radical degradation or cross-linking when subjected to a high compounding energy at a temperature above its melting point. In a first step (I), a thermoplastic organic polymer and an organopolysiloxane are mixed at a temperature at which both the thermoplastic organic polymer and the organopolysiloxane are in liquid phases to form a masterbatch. In a second step (II), the masterbatch is mixed with further thermoplastic organic polymer to form a polymer composition having a lower concentration of organopolysiloxane than that in the masterbatch. In the first step (I), the thermoplastic organic polymer and the organopolysiloxane are mixed in the presence of an additive capable of inhibiting the thermo-radical degradation or cross-linking of the thermoplastic organic polymer. The organopolysiloxane of the masterbatch remains stable during processing.
