摘要

This paper reports that two kinds of polymers with high infrared transparency and good mechanical and physical properties have been prepared. An internal standard method is used to evaluate the infrared transparency of the binders.The physical and mechanical properties of the binders are measured according to corresponding standards. The results show the absorbance of polymer A in 8-14 μm range is 26% that of the ethylene-vinyl acetate copolymer (EVA), and polymer B is 9% that of the EVA correspondingly. The film of polymer A shows good flexibility of above 1 mm, a hardness of grade 1, and adhesion of grade 2. The film of polymer B shows good flexibility of above 1 mm, a hardness of grade 1, and adhesion of grade 1.
