In attempts to improve the compatibility of
polypropylene (PP) with polyethylene terephthalate (PET), a
maleic anhydride grafted PP (PP-g-MA) was evaluated as a
compatibilizer in a blend of 30/70 wt % PP/PET. PP-g-MA
was produced from isotactic homopolymer PP utilizing the
technique of solid phase graft copolymerization.
