| 제목 | A study on the cure kinetics and phase separation of the Epoxy/CTBN-ATPEI-CTBN triblock copolymer/NMA |
| 초록 | To improve the toughness of epoxy resin in order to serve high-standard structural and mechanical component applications, carboxyl terminated nitrile rubber (CTBN) - amine terminated polyetherimide(ATPEI) ? CTBN triblock copolymer (ABA type) as an functionalized thermoplastic was introduced. In this study, the cure kinetics of an epoxy system containing the diglycidyl ether of bisphenol A (DGEBA) and nadic methyl anhydride (NMA) as a curing agent, and their blends with ABA triblock copolymer at 20wt% were studied. Also, In the curing process, two major reactions were observed and identified by using a multi-autocatalytic model equation for the cure kinetics. The co-continuous phase can be obtained in the range of high contents of ABA triblock copolymer(20wt% and 30wt%) at 120℃. |
