CAS: 87-40-1; 1,3,5-Trichloro-2-Methoxybenzene

该化合物是一种氯化芳香化合物,主要因其在食物,饮料和包装材料中作为污染物的作用而得到承认,因为其聚度极低,具有很强的芥子气味;通过微生物甲基化2,4,6-三氯苯酚形成,通常在cork或木制品中;在分析和质量控制应用中,TCA是检测和量化消费品中杂质的杂质的关键参考标准;其高度稳定性和低感官阈值使得对食品和饮料工业的污物和腐蚀性进行研究至关重要;由于其挥发性以及可能造成感官污染,需要适当的处理和储存.

标 题:Synthesis of a liquid polymer and a functionalized polymer
发明人：YAN YUAN-YONG
权利人:BRIDGESTONE CORP
摘要:A method comprising: (a) forming a living liquid polymer, wherein said living liquid polymer is anionically initiated and comprises a cation; (b) adding a functional initiator precursor of the formula FI-H, wherein H is hydrogen and FI is a functional group, said H terminates said living liquid polymer resulting in said liquid polymer having a number average molecular weight of about 20,000 (g/mole) to about 100,000 (g/mole), and said FI and said cation form a functional initiator; (c) adding monomer, wherein said functional initiator initiates anionic polymerization of said monomer; and (d) terminating the polymerization reaction initiated in step (c). Steps (a) through (c) may be conducted in a single reactor, allowing a liquid polymer to be dispersed in a functionalized polymer in a single polymerization step. Thus, the liquid polymer does not have to be handled separately and processing efficiency is improved.
