| 摘要 |
Vinylidene chloride (VDC) terpolymer (i) consisting of mer units derived from vinylidene chloride, a second monomer, e.g., vinyl chloride, and a third monomer, e.g., methyl acrylate, and (ii) having a melting point lower than the melting point of a VDC copolymer consisting of mer units derived from vinylidene chloride and the second monomer, is prepared by a batch suspension polymerization process comprising the step of contacting under batch suspension polymerization conditions vinylidene chloride, the second and third monomer, the third monomer having a reactivity ratio that is equal to or greater than the reactivity ratio of vinylidene chloride. |
