Advantages of polycarboxylic over dicarboxylic anhydrides in the melt modification of PPC

We present an alternative polymer modification of poly (propylene carbonate) (PPC). A conventional practice for PPC melt processing is the melt – modification with maleic anhydride (MAH) – a di-carboxylic anhydride –. In our work, PPC is melt-modified with pyromellitic di-anhydride (PDAH) – a tetra-...
