Additives with Dual Function -Acrylate Ester Copolymers as Modifiers for Engineering Polymers and as Carrier Resin for Masterbatches

摘要

Additives are generally perceived to improved product properties. Depending on the end use this polymeric additives can be used as impact modifiers, coupling agents or compatibilisers. In this paper a family of ethylene copolymers is described which are characterised through a very heterogeneous molecular architecture and thus an enhanced compatibility with other polymers and fillers. This allows them to fulfil two functions: they can be used as compatibiliser or impact modifier, but due to their high filler acceptance they are also useful as a carrier resin for masterbatches.
