Synthesis of Aromatic Linked Siloxane Based Triblock Copolymer Pre-Soft-Segment:

[Figure (not displayed)]

To a 100 ml separable flask fitted with a mechanical stirrer, 15 g of hydroxy terminated polydimethyl siloxane (DMS-S14 from Gelest Inc.) was added along with 5.36 g of di-chloro p-xylene (from Sigma) and 0.0089 g of Copper(II) acetylacetonate (Cu(Acac)2 from Sigma). The reaction mixture was refluxed at 110° C. for 5 hrs. At this point, 19.77 g of hydroxy terminated poly(propylene glycol) (from Sigma) was added dropwise and the reaction mixture was then refluxed for another 15 hr. The progress of reaction was followed by 1H-NMR and the final molecular weight, determined by gel permeation chromatography (GPC), was 3000 g/mol.

H-NMR analysis; Solvent used for 1H-NMR analysis is CDCl3.

Aromatic H=7.25-7.45 ppm, —CH2=4.5-4.6 ppm, —CH3 (of PPO)=1-1.4 ppm, —CH2 (of PPO)=3.2-3.8 ppm, —OH (of PPO)=3.8-4 ppm, —CH3(silanol)=0.5-0.8 ppm.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
