Species modification in macrocyclic polyester oligomers, and compositions prepared thereby

The MPO composition is performance, such as melting temperature, obtainable by changing one or more of performs the evolutionarily significant microarray and MPOs components by weight percentage. For example, and majority of tetramers, wherein with low temperature molten MPO composition. At the same time, the present invention relates to any one of the MPO composition of the heat-cured method, comprising the following steps: a) preparing a comprises at least two of MPOs composition; the (b) of the composition at least MPOs the weight percentage. The other, the present invention relates to a composition MPO, wherein the composition comprises at least two of MPOs, comprising up a melting temperature of MPOs content is less than or equal to 5%. The other, the present invention relates to a MPO composition, comprising: 30-40% The polyester, a 30-45% of the polyester tripolymer, 0-5% of the polyester tetramers, 5-20% of the polyester is a body.
