摘要

Demanufacturing of electronics invariably results in one or more plastics waste streams with different amounts of thermoplastics (principally from housings) and thermosets (principally from circuit boards) which are inherently incompatible and not recyclable with thermoplastics - at least to materials with mechanical properties that are useful. Extensive sorting is expensive, but can minimize the contamination of both thermoplastic and thermoset waste streams, but does not solve the problem - poor mechanical properties still result. An alternative route is the avoidance of sorting and the use an "in-situ" reactive compatibilization route to achieve stress-transfer between the thermoplastics and thermoset phases yielding good mechanical properties. This reactive extrusion compatibilization route has been utilized to convert post-consumer plastics (containing 5 different thermoplastics) from a weak, brittle material when melt blended into a tough, ductile polymeric alloy that has applications in the automobile industry, housing, office, home and other consumer products. Examples of this type of technology for recycling toner, whole carpets, automotive components and tiers will also be briefly presented, if time permits.
