Patent number: 9388310Abstract: A composition that contains from 30 to 95 wt. %, based on the total weight of the composition, of a thermoplastic component and an effective amount of a flow-enhancing component. The effective amount of the flow-enhancing component reduces the viscosity of the composition by at least 10% compared to the viscosity of a composition comprising the thermoplastic component, but not an effective amount of the flow-enhancing component. The thermoplastic component is selected from the group consisting of polycarbonates, polyesters, and combinations thereof. The flow-enhancing component comprises b1) a component selected from the group consisting of metal oxides, metalloid oxides, metal alkoxides, metalloid alkoxides, and combinations thereof and b2) a mineral filler component. The weight ratio of component b1) to component b2) ranges from 1:25 to 25:1. A method for enhancing the flow of compositions comprising thermoplastic components is also disclosed.Type: GrantFiled: January 16, 2015Date of Patent: July 12, 2016Assignee: SABIC GLOBAL TECHNOLOGIES B.V.Inventors: Josephus Gerardus M. van Gisbergen, Chris van der Weele, Sreepadaraj Karanam, Mark Adrianus Johannes van der Mee
