One of the inherent problems in the recycling of polymers involves the wide variety of immiscible and incompatible polymer resins. For this reason, it is important to keep scrap from different sources separate, especially if it is known beforehand that the compositions are significantly different. Approaches to upgrading the performance of the scrap streams can then be tailored to each stream. Our work has been based, in part, upon one such approach. Reactive rubbery polymers have been used to modify several recycle streams. These models represent household scrap, business machine housings, and automobile bumpers. Dramatic property improvements can be obtained if specific reactive rubbery polymers are matched to certain recycle streams. Also, it was found that variability in the source and the composition of a given stream over time can dramatically affect results. These findings underscore the inherent difficulty in developing a universal approach to the recycling of mixed plastics.
