Claims12
A process for dissolving a polyol modified polyalkylene terephthalate, the process comprising:
- dissolving a polyol modified polyalkylene terephthalate in a solvent to produce a dissolved polyol modified polyalkylene terephthalate,
- the polyol modified polyalkylene terephthalate having been obtained by a continuous process comprising:
- introducing components in a continuous reactor comprising a reaction zone, the components including a polyalkylene terephthalate, a polyol, and a transesterification catalyst;
- reacting the components in the reaction zone of the reactor at a temperature in the range of 180° C. to 350° C. to produce the polyol modified polyalkylene terephthalate;
- wherein the polyol includes one or more of tris(2-hydroxyethyl) isocyanurate and glycerine, and
- wherein reacting the components is performed in a melt of the polyalkylene terephthalate.
