1. a preparation method for heat resistance modified chinlon 56 polymer, comprises the steps:

  • (1) under nitrogen protection, bio-based pentanediamine and adipic acid react in water, obtain chinlon 56 salineSolution;

    Described bio-based pentanediamine is lysine or lysinate is sloughed two end carboxyl under the effect of E.C. 4.1.1.18 and obtainedArrive;

    (2) described chinlon 56 saline solution and molecular weight regulator are added to reactor, in temperature be210~

    240 DEG C and pressure are to carry out pressurize under conditions of 1.7~

    1.85MPa;

    Discharge the pressure in described reactor and addAfter heat-proof modifier, temperature is risen to 265~

    275 DEG C;

    Evacuation also agitated obtains heat resistance modified chinlon 56 polymer.
