After 1 h ultrasonic treatment, the solution was dropped in TMEDA
(0.2 mL/10 g casting solution) and kept stirring vigorously for 10 min.
1mL/0.219 mmol APS was added from the 5 g/100 mL APS solution and 1mL/0.086mmol TMEDA
was added from the 1% TMEDA
For example, industry leaders could participate in industry academe workshops on TM education such as the one recently conducted at MIT by TMEDA
. Similarly, mid-level managers in technology-based firms could initiate contact with their local TM school and help the program director devise a portfolio of appropriate joint activities such as the ones described earlier.
with the weight ratio of 2:1, were dropped into the solution respectively.
The DMP, vanadium and its oxides, and amines such as pyridine and TMEDA
as ligand were used to obtain PPO.
When n-BuLi was previously mixed with THF or TMEDA
and then added into the screw, styrene could be copolymerized with alkadiene and the reaction speed would be increased.
Anhydrous ethyl ether, methanol, tetrahydrofuran (THF), thiophene, and N,N,N', N'-tetramethylethylenediamine (TMEDA
) were purchased from Kermel Chemical Reagents Development Center (Tianjin, China).
The ATRP initiation system consisted of copper (I) bromide (CuBr, 98%) as the catalyst, methyl [alpha]-bromophenylacetate (MBPA, 97%) as the initiator, N,N,N,N-tetramethylethylenediamine (TMEDA
, 99.5%) or N,N, N, N-pentamethdiehtylenetri-amine (PMDETA, 99%) as the ligand.
