New vinyl ester copolymers as stabilizers for dispersion polymerization in scCO2 |
| 초록 |
In this paper we demonstrate new poly vinyl alkylate homopolymers and copolymers with excellent solubility in scCO2 that can be used as stabilizers for dispersion polymerization in scCO2. Poly (vinyl acetate) (PVAc) was combined in various ratios with poly (vinyl butyrate) (PVBu) and poly (vinyl octanoate) (PVOc) to both tune the scCO2-solubility and provide adequate steric stabilization. The polymer cloud points observed were found to be dependent on the ratio of the different blocks and the molecular weights and polydispersities (PDI) of the polymers. The effectiveness of these new polymeric stabilizers for dispersion polymerization of N-vinyl pyrrolidone (N-VP) in scCO2 is presented. |
