Abstract
AbstractTriblock and three arm, poly(ether amide) star block copolymers have been synthesized and characterized. Di‐ and tri‐functional amine terminated polyethers were reacted with caprolactam at elevated temperatures to produce the block copolymers. The polyether amines were incorporated at levels ranging from 5%‐40%. Differential scanning calorimetry(DSC) evaluation reveals no reduction in the crystalline melting point of the polycaprolactam end blocks up to 40% polyether incorporation. Dynamic mechanical spectroscopy and FTIR were used to confirm the incorporation of the polyether. A comparison is made between triblock and star block copolymers, and between poly(propylene glycol) and poly(ethylene glycol) polyether midblocks. These block copolymers have improved impact performance as well as a flexural modulus that first increases and then decreases as the amount of polyether is increased in the block copolymer.
