DEPROTEINIZING AGENT NATURAL RUBBER AND PRODUCTION OF DEPROTEINIZED NATURAL RUBBER USING SAME

摘要

PURPOSE:To obtain this agent which can eliminate simply and effectively protein from natural rubber by compounding protease and a specific anionic surfactant as the effective components. CONSTITUTION:The agent contains, as the effective components, protease and at least one anionic surfactant selected from the group consisting of anionic surfactants based on a sulfonic acid, a sulfuric ester, and a phosphoric ester (e.g. a sodium alkylbenzenesulfonate, a sodium alkylsulfate, and a sodium alkylphosphate) pref. in a wt. ratio of protease to the surfctant of (1:1)-(1:200). A deproteinized natural rubber is produced at a high productivity by adding 0.01-10wt.% the agent to a natural rubber latex.
