如何查找COA批号
批号可以在产品标签上"批“ (Lot或Batch)字后面找到。
如果您查询到的批号为 TO09019TO 等,请输入去除前两位字母的批号:09019TO。
如果您查询到的批号含有填充代码(例如05427ES-021),请输入去除填充代码-021的批号:05427ES。
如果您查询到的批号含有填充代码(例如 STBB0728K9),请输入去除填充代码K9的批号:STBB0728。
部分情况下,可能未在线提供COA。如果搜索不到COA,可在线索取。
RAFT (Reversible Addition Fragmentation chain Transfer) polymerization is a reversible deactivation radical polymerization (RDRP) and one of the more versatile methods for providing living characteristics to radical polymerization.
RAFT(可逆加成断裂链转移)聚合是一种可逆的去活化自由基聚合(RDRP),是给自由基聚合赋予活性的通用方法之一。
The manufacture of monomers for use in ophthalmic applications is driven by the need for higher purity, improved reliability of manufacturing supply, but ultimately by the need for the increased comfort, convenience, and safety of contact lens wearers. Daily wear contact lenses have the potential to fill this need for many customers; however, their widespread use is constrained by higher costs compared to weekly- or monthly-based lenses. New approaches that improve cost structure and result in higher quality raw materials are needed to help make contact lenses more affordable and accelerate growth of the contact lens market.
We presents an article about ARGET ATRP, and its procedure for PMMA polymer brush growth. Surface preparation before polymer brush growth consists of two steps: surface cleaning and initiator monolayer deposition.
Monodisperse, surfactant-free polymer spheres for use as colloidal crystal templates can be easily obtained in reasonably large quantities. Typical synthesis methods for poly(methyl methacrylate) (PMMA) and poly(styrene) (PS) by emulsifier free emulsion polymerization are described below and yield spheres several hundred nanometers in diameter.
RAFT (Reversible Addition-Fragmentation chain Transfer) is a form of living radical polymerization involving conventional free radical polymerization of a substituted monomer in the presence of a suitable chain transfer (RAFT) reagent.
RAFT(可逆加成-断裂链转移)是一种活性自由基聚合反应,在有适合的连转移(RAFT)试剂存在下发生的非传统的取代单体自由基聚合反应。
