PROCESS FOR THE MANUFACTURE OF POLYCYCLOHEXANE DIMETHYLENE TEREPHTHALATE COPOLYMERS FROM POLYETHYLENE TEREPHTHALATE, AND COMPOSITIONS AND ARTICLES THEREOF |
摘要 |
A process comprises heating at a first temperature under an inert atmosphere and at a first pressure of at least 101 kPa a cyclohexanedimethanol, and a polyethylene terephthalate component selected from the group consisting of polyethylene terephthalate and polyethylene terephthalate copolymers, to form a molten mixture; and heating the molten mixture with agitation at a second temperature higher than the first temperature and a second, subatmospheric pressure for a time and under conditions effective to form a modified polycyclohexane dimethylene terephthalate copolymer comprising at least one residue derived from the polyethylene terephthalate component. |
