| titleOfInvention | The preparation method of copolymerized polymer |
| abstract | The invention discloses the preparation method of a kind of copolymerized polymer, including first stage esterification, second stage esterification, phase III prepolymerization reaction and fourth stage polycondensation reaction at end, wherein, in first stage esterification, various ingredients is individually allocated and is esterified.Compared with prior art, the present invention uses various ingredients to be individually esterified, and further mixes the mode of copolymerization, it is therefore an objective to make each component to be esterified uniformly, it is to avoid to cause certain component not uniformly to be esterified because of the difference of esterifying efficiency.The component of more difficult esterification can be made to carry out ester exchange more fully, it is easier to be embedded in the macromolecular chain of polycondensation, end product quality improves simultaneously.Component is changed convenient and swift simultaneously, is unlikely to produce a large amount of Transition Materials and increase production cost, and conversion efficiency is also greatly improved. |
