Resum
Boltorn H30 hyperbranched polyester has been modified by acylation with 10-undecenoyl chloride to obtain HBPs with different degree of modification. These HBPs have been used as reactive modifiers, in a proportion of 5 and 10%, of DGEBA/MHHPA/BDMA formulations. The materials obtained have been characterized and their mechanical properties evaluated. Depending on the degree of modification of the HBP, homogeneous or phase separated materials were obtained, which influence the properties. When the...
