CRYSTALLIZABLE THERMOPLASTIC RESINS AND DENDRIMERS WITH IMPROVED FABRICATION CHARACTERISTICS
Application 24/MUMNP/2006 published 2006-09-01, filed 2006-01-05
The strain-hardening characteristics and melt rheology of thermoplastic resins including crystallizable polyester resins are modified by blending with a dendrimeric modifier. Blends comprising PET resins and up to about 2 wt.% of a dendrimer have increased melt strengths and exhibit a reduction in strain-hardening parameter, reflected in a lower strain level at the onset of strain hardening. Blends further comprise PET resins and a component comprising a ratio of dendrimer modifier to purified terephthalic acid. Drawing: 5 Sheets Total Pages: 31 Fig. 1
