Abstract: A process for the for the preparation of dynamically vulcanized thermoplastic elastomers is described. The process comprises melt processing under high shear conditions A) at least one thermoplastic engineering resin, B) at least one vulcanizable rubber, C) a curing agent or curing agents, and D) at least one additional thermoplastic engineering resin in the form of solid particles having an effective diameter of not less than 0.05 mm, wherein said solid particles D) are added to a molten mass of A), B) before, during or after the addition of C) but prior to substantial completion of the vulcanization of B). The process provides a means to avoid substantial degradation or unwanted cross-linking of the thermoplastic engineering resin and provides a means of controlling the reaction temperature during the curing, vulcanization, or cross-linking of the rubber.

Abstract: An open roof construction of a vehicle comprises a closure element that mates with a roof opening, which closure element is movable along a first longitudinal guide and a second longitudinal guide. To this end, the closure element includes a front support, which is supported in the first longitudinal guide, and a guide element, which is slidable in the second longitudinal guide. An adjusting element, which is movable in the longitudinal direction by means of an actuating element being driven from the drive unit, is disposed under said closure element, which adjusting element is fitted with the guide element and which is arranged for moving the guide element into and out of engagement with the second longitudinal guide. Optionally, the adjusting element moves laterally during the longitudinal movement.

Abstract: A method to improve cling force of a stretch film by compounding linear low density polyethylene with ultrafine zinc oxide having a mean particle size of less than about 0.05 micrometers prior to forming the film.
