THE CURE TECHNOLOGY OF MODIFIED BISMALEIMIDE AND CYANATE ESTER RESIN

Abstract

Abstract:

The cure system,with a organometallic salt as catalyst,of cyanate(CE) and bismaleimide(BMI) modified by DBA was studied by DSC,and the kinetic parameters were obtained by Kissinger and Crane formula.The system's cure technology was determined by IR and cure degree.Two cure stages were detected,which is belonging to the CE and modified BMI,respectively,due to the accelerating effect of the existence of catalyst on the cure process of CE.By analysis,the cure cycle was 170℃/2h,225℃/2h,240℃/2h,which made the curing reaction occurring completely forming the IPN polymer.

Key words: modified bismaleimide, cyanate ester, cure technology
