（1）采用熔融预聚二步法合成了硬段含量为35%，R为0.98的GAP基含能热塑性弹性体，采用红外及热重表征，说明聚氨酯基团被成功引入含能热塑性弹性体，弹性体热分解在250℃左右，其热稳定性略高于GAP。

（2）采用显微镜观测样品，得到样品的微观显微图像，用阈值处理技术将显微图像转化为二值图，统计颗粒边缘间距并计算分散度D值。将此评价方法实际应用于热塑性弹性体复合材料分散均匀性的描述，验证了该定量评价方法的可行性。

Title  The research of Energetic thermoplastic elastomer and its application technology                                  

Abstract

a glycidyl azide polymer (GAP)-Energetic thermoplastic elastomer (GAP-ETPE)  was compounded. A quantitative description method was proposed to evaluate dispersion  uniformity of high solids of  high solids Energetic thermoplastic elastomer composites system .High solids thermoplastic elastomer composites preparation technology was studied. The results show:

(1) the hard segment content of 35%, R of 0.98 Energetic GAP base thermoplastic elastomers was compounded through molten prepolymerization two-step method.The results of IR show that GAP containing urethane groups. The results of TG show that decomposition Temperature of Energetic thermoplastic elastomers was around 250℃ and  thermal stability higher than GAP.

(2) The sample was observed by microscopy.the micro sample microscopic image obtained. the  microscopic image was translated into the binary image through threshold processing technology.  counting the edge of the particle spacing and calculating the value of the degree of dispersion D which can be used as the evaluating indicator to evaluate the uniformity. This evaluation method is actually applied to the thermoplastic elastomer dispersed composite description of a method to verify the feasibility of quantitative evaluation.

(3) For the high solid content of thermoplastic elastomer composite system, semi-solvent prepared sample. the process conditions as the solvent less than 0.2, the extrusion molding temperature of 50 ℃ was determined by comparing the test.
