pre-treated seed

The preferred polymerization conditions were that seed polymer temperature 80 ℃, pre-emulsion distribution droplets time 1.5 h, shell polymerization temperature 75~ 80 ℃, distribution droplets time 5 h.

较佳的聚合工艺为：种子聚合温度80℃，预乳化液滴加时间15h；壳层聚合温度75～80℃，滴加时间5h。

A kind of emulsion pressure sensitive adhesive with good heat and water resistance was prepared by using pre-emulsification seed polymerization and adding self-crosslinking monomer NMA and reactive emulsifying agent AMPS in acrylate.

采用预乳化种子聚合工艺，在多元丙烯酸酯中添加自交联功能单体N-羟甲基丙烯酰胺和反应型乳化剂2-丙烯酰胺基-2-甲基-丙基磺酸铵盐，研制出性能优异的耐热耐水型乳液压敏胶。

If you are a risk-taker and enjoy the challenges and roller-coaster ride, then the jungle phase is for you and you should bias towards seed funded or recently series a funded companies that are pre-revenue.

如果你愿意承担风险，享受挑战和坐过山车一样的感受，那么你适合丛林阶段，可以优选那些处于种子阶段融资的企业或最近刚刚获得首轮投资但尚未实现收入的企业。

In 2004 Hebei Production Test, Seed cotton yield and lint yield and pre-frost lint yield increased 14.1%, 29.0% and ( 38.5%) than DP99~ ( B). Seed cotton yield was first in same group.

2004年生产试验，籽棉、皮棉和霜前皮棉产量分别较对照DP99B增产14.1%，29.0%和38.5%，籽皮棉产量均居第1位；
