Rubber We all know what rubber is.
We have seen it on the wheels of cars ; we have used it to rub out mistakes in drawing ; we have played games with rubber balls.
When we press a piece of rubber we change its shape.
But as soon as we stop pressing, the rubber springs back to its first shape ; we therefore say that rubber is elastic.
Rubber was first used to make rubber balls.
In 1492, Columbus sailed from Spain and discovered America.
One of the many strange things which he and his men saw in America was a game played with rubber balls.
They noticed that the rubber balls bounced much better than the balls which they had used in their own country.
When they sailed home again they told their friends that the balls were made from the gum of a tree.
Hundreds of years had passed before rubber was used in Europe and other parts of the world.
Small pieces of rubber were brought to Europe, and kept by people who liked to collect strange things ; but no one thought that rubber could be useful.
Then an artist found out that rubber would rub out pencil marks.
That was one of the first uses of rubber, and that is how it came to be called 'rubber'.
Rubber trees grow only in countries where it is very hot and very damp.
These countries are near the equator ; so it was in the countries near the equator that men went out to hunt for the rubber trees.
It was not easy to find the trees.
In those hot damp lands, trees of many kinds grow so close together that it is difficult to travel through the forests.
The men who were hunting for rubber trees found them growing wild in South America, in Central America, and in West Africa.
Nearly all the world's rubber came from the great forests of America and West Africa.

The Development of Rubber Here is the story of rubber.
From the earliest time it was common knowledge the Peruvians that when a cut was made in the outside skin of a rubber tree , a white dliquid milk came out , and that this a sticky mass of rubber might be made .
This rubber is soft when warm, so that it is possible to give it any .
The Peruvians made the that it was very good for keeping out the wet.
Then in the early 1800's , the Americans made use of it for the first time .
First they made overshoes to their feet dry.
Then came a certain Mr.
Mackintosh, who made coats of cloth covered with natural rubber.
From that day to this we have been coating cloth with rubber as Mr.
Mackintosh, and our raincoats are still named after him.
But these first rubber overshoes and raincoats were all soft and sticky in summer, and and inelastic in the winter when it was cold.
But the rubber we have today is soft and elastiс, very strong - even in the warmest summer and the coldest winter.
This was made by a man called Goodyear.
After many , he found that nitric acid made the rubber much better, but it is not hard and strong enough.
Then a strange thing took .
A friend of his , Nicholas Hayward, had the idea in his sleep that rubber might be made hard and strong if mixed with sulphur and put in the sun.
Goodyear put this idea the test, and saw that it did have more or less the desired effect - though somewhat less than more.
The only effect it had was on the outside of the drubber.
It is common knowledge now that the to make rubber hard and strong is by heating dit with sulphur.

Rubber
Natural rubber is an elastic substance found as milky dispersion in many specics of plants.
Synthetic rubbers are highly polymeric substances manufactured from a wide range of chemical compounds.
Both synthetical and natural rubber have in common the ability to undergo nearly reversible, highly elastic deforma¬tion.
, f
In 1960, world wide use of rubber was divided nearly equally between natu¬ral product (about 2 million tons) and synthetic rubr ber (about 1, 8 million tons).
Natural rubber being an extremely valuable substance, many other naturally occurring compounds are closely related to it, chemically.
The basic building block for natural rubber as well as other polyisoprenoids is acetic acid.
Natural rubber was first obtained from wild trees in Brazil.
The physical and chemical properties of natural rubber are fixed by biologi¬cal factors.
In synthetic rubber a much greater variation of properties can be real¬ized.
The chemical properties of rubber are of paramount importance.
Vulcanization is a process used jto make raw rubber useful.
It decreasessen - sitivity to extremes of temperature, confers resistance to flow under stress and sta¬bilizes rubbers valuable properties.
Chemically, vulcanization creates strong bonds between the long linear molecules of the rubbery polymer.
It fixes efficiently the molecules position with rcspect to one another and prevents their slippage under¬stress.
