PROCESS FOR FORMING ARTICLES DIRECTLY FROM MELT POLYMERIZATION

摘要

The present invention provides a process comprising the steps of a) melt reacting at least one glycol and at least one dicarboxylic acid to form a polyester having an IhV of at least about 0.5 dl/g, wherein said at least one glycol is selected from the group consisting of glycols having up to 10 carbon atoms and mixtures thereof and said dicarboxylic is selected from the group consisting of alkyl dicarboxylic acids having 2 to 16 carbon atoms, aryl dicarboxylic acids having 8 to 16 carbon atoms and mixtures thereof; and b) forming said polyester into shaped articles directly from step a). Thus, the present invention provides a direct melt to mold process for forming polyester articles.
