...Tirthankar Jana; Tapan Kumar Dhar Purpose The purpose of this study is development of a novel hybrid polymer emulsion through graft copolymerization onto hyperbranched alkyd using monomers like vinyl acetate ( VAM ) and vinyl ester of versatic acid 10 (VeoVa 10) combination followed...

... hyperbranched polyester (HBP) was conceptualized and synthesized to enhance the toughness and dielectric properties of EP. Design/methodology/approach Using P-toluene sulfonic acid (p-TSA) as the catalyst and Bis(hydroxymethyl)propionic acid (DMPA) as the branching unit with pentaerythritol (PER...

...Tirthankar Jana; Tapan Kumar Dhar Purpose The purpose of this paper is to develop an inorganic-organic hybrid emulsion polymer using grafted hyperbranched alkyd modified with nanometal oxide and to study the performance of the developed hybrid emulsion in paint formulation with respect...

...Jiahao Shi; Ling Weng; Xiaoming Wang; Xue Sun; Shuqiang Du; Feng Gao; Xiaorui Zhang Purpose Epoxy resin (EP) is a kind of thermosetting resin, and its application is usually limited by poor toughness. In this case, a type of new flexible chain blocking hyperbranched polyester (HBP) was designed...
