The viscosity and gel time of resin system of modified bismaleimide(BMI) resin with rigid polyetherimide(PEI) and the mechanical properties of PEI/BMI/RS/ glass composite materials were studied.
A new kind of epoxy resin adduct polyol (EAP) with rigid backbone was synthesized by the reaction of bisphenol - a type epoxy resin with acetic acid and characterized with FTIR and 1h - NMR.
Tensile strength of LDPE resin low voltage differential, rigid poor dimensional stability when processing poor, and connection difficulties, not suitable as a water supply pressure tube material.
