Rheological　behavior　of　the　copolymer　resin　of　allyl　condensed　polynuclear　aromatic(COPNA)　resin　and　bismaleimide(BMI)　for　solid　lubricant　composite　was　studied　with　differential　scanning　calorimetry(DSC)　analysis　and　viscosity　experiments.　A　rheological　model　based　on　Dual-Arrhenius　equation　was　established　and　used　to　simulate　and　forecast　the　rheological　behavior　of　the　resin.　The　results　indicate　that　the　established　rheological　model　for　relative　viscosity　is　in　good　agreement　with　Dual-Arrhenius　equation　in　the　temperature　range　of　120°C~160°C.　The　initialized　viscosity　of　the　resin　decreases　with　increasing　temperature,　and　the　relative　viscosity　increases　with　increasing　time　at　certain　temperature.　The　ideal　processing　temperature　of　the　resin　is　about　150°C　in　terms　of　the　rheological　model.
