## Abstract Blends of a tetrafunctional epoxy resin, tetraglycidylโ4,4โฒโdiaminodiphenylmethane (TGDDM), and a hydroxylโfunctionalized hyperbranched polymer (HBP), aliphatic hyperbranched polyester Boltorn H40, were prepared using 3,3โฒโdiaminodiphenyl sulfone (DDS) as curing agent. The phase behavio
A liquid diglycidyl ether of bisphenol A (DGEBA) epoxy resin is blended in various proportions with amine-terminated polyoxypropylene (POPTA) and cured using an aliphatic diamine hardener. The degree of crosslinking is varied by altering the ratio of diamine to epoxy molecules in the blend. The mixt
