In this contribution, polyesters and polyurethanes were synthesized by step-growth polymerization in which alkyne pendant groups are located along the backbone. This was achieved via the use of different alkyne-based diols. For the polyesters, for which the synthesis occurs at high reaction temperatures, it has been proven that the alkyne functions are resistant upon heating. Thereafter, these universal alkyne-functionalized materials were used as a platform to further modify and broaden the properties of industrially relevant polymers. Click chemistry, which has recently been emerged as a powerful functionalization tool in polymer science, was used to modify the properties of these polyesters and polyurethanes. The desired functionality could be anchored by choosing the appropriate azide component. The post-functionalization via the Huisgen 1,3-dipolar cycloaddition was carried out in different reaction conditions leading to complete yields in all cases. |
