【摘要】 本文提出以瘐烷作溶剂,用粘度法测定甲基乙烯基生胶的分子量。经试验结果证明:本法与标准法用甲苯作溶剂测得的结果相一致。本法具有溶剂毒性小,溶解性好,准确度高,操作简便等优点。更多还原

【Abstract】 This paper uses viscometry to determine molecular weight of the methylethylenvinyl gum using heptane as solvent.The test results indicate that method got the same result as the standard method using methylbenzene as solvent.It is characterized by less solvent toxicity,better dissolvability,higher sensitivity and simplicity.更多还原
