摘　　要：探讨了专用复合添加剂对工业化生产透明线型低密度聚乙烯(LLDPE)农用地膜专用树脂的影响。结果表明,新型树脂力学性能与原树脂的相当,雾度明显下降;差示扫描量热法(DSC)测试表明,新型树脂结晶度明显高于原树脂的,且晶体尺寸有变小趋势;二维偏光显微镜(DPLS)测试显示新型树脂内部球晶尺寸下降,球晶结构明显改善。The effect of special composite modifier on transparent LLDPE new resin was discussed. Measurement results show that new resin has the same mechanical properties comparing with original resin, the haze of the new film decreases significantly. DSC results show that the crystallinity of the new film goes up,and the spherulite size decreases. DPLS results show that spherulite size becomes smaller and structures are improved.
