Method for preparing polyester compositions of high melt viscosity by reaction with polyeopxides |
| abstract |
Branched polyesters, prepared by the reaction of a polyester such as poly(butylene terephthalate) with a polyepoxy compound such as triglycidyl isocyanurate, are annealed at a temperature above the glass transition temperature of the polyester but below the melting and/or decomposition temperature. The annealed compositions have higher melt viscosities and impact strengths than similar compositions which have not been annealed. |
