As a result of these assumptions, a conversion slightly higher than that predicted by the Flory–Stockmayer Theory is commonly needed to actually create a polymer gel. Since steric hindrance effects prevent each functional group from being equally reactive and intramolecular reactions do occur, the gel forms at slightly higher conversion. [5]
Random graph theory of gelation is a mathematical theory for sol–gel processes.The theory is a collection of results that generalise the Flory–Stockmayer theory, and allow identification of the gel point, gel fraction, size distribution of polymers, molar mass distribution and other characteristics for a set of many polymerising monomers carrying arbitrary numbers and types of reactive ...

The lari (Georgian: ლარი, pronounced; ISO 4217: GEL) is the currency of Georgia.It is divided into 100 tetri (თეთრი).The name lari is an old Georgian word denoting a hoard, property, while tetri is an old Georgian monetary term (meaning 'white') used in ancient Colchis from the 6th century BC.

The economy of Europe comprises about 748 million people in 50 countries. Throughout this article "Europe" and derivatives of the word are taken to include selected states whose territory is only partly in Europe, such as Turkey, Azerbaijan and Georgia, and states that are geographically in Asia, bordering Europe and culturally adherent to the continent, such as Armenia and Cyprus.
In polymer chemistry, the gel point is an abrupt change in the viscosity of a solution containing polymerizable components. At the gel point, a solution undergoes gelation, as reflected in a loss in fluidity. After the monomer/polymer solution has passed the gel point, internal stress builds up in the gel phase, which can lead to volume shrinkage.
The following list provides information relating to the minimum wages (gross) of countries in Europe. [1] [2]The calculations are based on the assumption of a 40-hour working week and a 52-week year, with the exceptions of France (35 hours), [3] Belgium (38 hours), [4] United Kingdom (38 hours), [3] Germany (38 hours), [5] Ireland (39 hours) [5] and Monaco (39 hours).
