【摘要】 本文是根据醋酸乙烯酯的羰基伸缩振动频率位移与单体在共聚物中联接几年的关系,在无己知组成的共聚物的条件下,采用不纯样的定量分析方法,选用1740cm^-1和1660cm^-1峰进行共聚物的红外光谱测定,进而求出两单体的竞聚率及其共聚物的序列分布。更多还原

【Abstract】 In this paper, according to the re’ation between the frequeney displacement of vinyl acetate’s carbonyl streching vibration and the mating probatility of monomer in the copolymer, under the condition of unknow composition, using impure sample analysis, selcting 1740cm-1 and 1660cm-1 heights, the two monomers’ reactivity ratio and its copolymer’s alignment distributi are found out by lnfrared spcctroscopy.更多还原
