It was shown from the results that emulsifier TP-Ⅴ which was prepared by PEG 4000 reacted with TME, in the molar ratio of TME to PEG 2:1, at about 110℃ for 1 h, catalyzed by boron trifluoride diethyl etherate, has a very good emulsifying impact for TME. Particle size distribution of the emulsion was homo-geneous and viscosity of the emulsion was small.
实验结果表明,以M相对适中的PEG4000与TME按物质的量比2: 1、在催化剂三氟化硼乙醚作用下、110℃左右反应1h合成的乳化剂TP-Ⅴ,对萜烯基环氧树脂具有很好的乳化效果,制备的乳液粒子粒径均一度较高,乳液表观黏度较小。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.
