The present invention provides a post-treatment method of a vinyl chloride-based polymer including: (a) preparing a stream containing vinyl chloride-based polymer powder and unreacted vinyl chloride-based monomers by drying a vinyl chloride-based polymer latex in a drying unit; (b) filtering the stream containing the vinyl chloride-based polymer powder and the unreacted vinyl chloride-based monomers in a filtering unit; and (c) recirculating a gas containing the unreacted vinyl chloride-based monomers discharged from the filtering unit to a latex storage unit.

In various embodiments, the invention relates to poly(propylene fumarate) (PPF)-based star-shaped copolymers synthesized using a core-first approach that uses a multi-functional alcohols as an initiator, and Mg(BHT).sub.2(THF).sub.2 as catalyst for controlled ring opening copolymerization (ROCOP) of maleic anhydride (MAn) with propylene oxide (PO). In some embodiments, these star-PPF copolymers have lower viscosities than their linear analogs, allowing a decrease in DEF fraction in resin formulation, as well as the use of higher molecular weights. These star-shape PPF can be used to prepare PPF:DEF resins containing as much as 70% by weight of the multi-arm PPF star copolymers, and have a low complex viscosity of high M.sub.n star PPF resin that affords rapid printing with a M.sub.n nearly eight times larger than the largest linear PPF oligomer printed previously.
