Question

Give the structure of the polyurethane formed by the reaction of toluene diisocyanate

with bisphenol A.

Short answer

Polymer polyurethane is made by a condensation reaction of alcohols (bisphenol A) with compounds that contain an isocyanate group (toluene diisocyanate).

Step-by-step solution

Reaction

Polymer polyurethane is made by a condensation reaction of alcohols (bisphenol A) with compounds that contain an isocyanate group (toluene diisocyanate).

Structure

Polyurethane is a synthetic polymer, that has urethanegroups in their chains. It have asegmented structure. A hard segment derived from the isocyanates and soft segments from the diols are normally formed.
