carbonyl group

A functional group with a carbon atom double-bonded to O2; the 2 remaining bonds are free to attach to other molecules.

Examples of carbonyl compounds
Aldehydes, amides, acyl halides, amides, carboxylic acids, esters, and ketones.

carbonyl group (kärˑ·b·nil grōōpˑ),

n a functional group in which a carbon atom is joined to an oxygen by a double bond; found in aldehydes and ketones.

This could be due to the PTEG polyether nature, able to create stronger hydrogen bonds with the N--H bonds than the urethane carbonyl group as mentioned in FTIR analysis [20].
This might come from the strongest mesomeric effect, which produced from the delocalization of the unshared electrons of oxygen throw the furan ring into the [alpha], [beta]-unsaturated carbonyl system to accommodate a negative charge on the oxygen of the carbonyl group Scheme 2, which might make the compound less antibacterial active compared with other substituted [alpha], [beta]-unsaturated carbonyl compounds.
With respect to the side reaction, FTIR also confirms the existence of other function group, such as carbonyl group (-OH) and hydroxyl group (-C=0) in dissoluble parts.
As in the polyester-based TPUs, the carbonyl group is present on both the soft and hard segments, hydrogen bonding can occur between HSs or between hard and soft segments.
