To develop a gel like substance which could
be used in post nasal operation

Current widely used products available to control
nasal bleeding are base on sponge and balloon
types. This products are not comfortable for the
patient throughout their use and especially
during removal of the product.
Recently a German company has come up with
antibiotic gel which needs to be mixed before
use and harden in the nose. Apart from being
very expensive, the problem with this product it
takes a long time to disintegrate and most of the
time it need to be removed manually thus cause
discomfort to patients

Liquid form in room temperature
Change to gel form in body temperature
Disintegrate with time preferably in 48 hours

This invention relates to normally liquid, stable
polymer/polyol compositions formed by polymerizing, in
the presence of a free radical catalyst, an ethylenically
unsaturated monomer or monomers dissolved or
dispersed in a polyol mixture including a coupled polyol
consisting of the reaction product of a polyol having a
functionality in excess of 2 reacted with polyisocyanate in
such proportion that the ratio of hydroxyl groups to
isocyanato groups is greater than 1. In one embodiment,
the coupled polyol is made in situ in the base polyol by
addition thereto of the required amount of the
polyisocyanate. The novel polymer/polyol compositions
are convertible to polyurethane foams and elastomers.
