POLYESTERS

 Condensation polymerisation can also be used to make other polymers with properties different from those of nylons. Polyesters are condensation copolymers made from two monomers. One monomer has an alcohol group (---OH) at each end. When the monomers react, an ester link is formed, with water being lost each time. 

One each polymers has the trade 'Terylene'. Like nylon, Terylene clothing is generally softer than that made from nylon. The ester linkage that joins the monomer units in the man-made fibre Terylene can be broken down by acid or alkaline hydrolysis. So it is not good news if spots of alkali fall on your shirts or sweaters!

THE STRAWBERRY PINK VILLA

Image
                                                      The villa was small and square, standing in its tiny garden with an air of pink-faced determination. Its shutters had been faded by the sun to a delicate creamy green, cracked and bubbled in places. The gardens, surrounded by tall fuchsia hedges, had the flower-beds worked in complicated geometrical patterns, marked with smooth white stones. The white cobbled paths, scarcely as wide as a rake's head, wound laboriously round beds hardly of stars, half-moons, triangles, and circles, all overgrown with a shaggy tangle of flowers run wild. Roses dropped petals that seemed as big and smooth as saucers, flame-red, moon-white, glossy, and unwrinkled; marigolds like broods of shaggy suns stood watching their parent's progress though the sky. In the low growth the pansies pushed their velvety, innocent faces through the leaves, and the violets drooped sorrowfully under their heard-shaped leaves. The bougainvillaea that sprawled luxur

Methanol is very toxic and in small amounts can cause blindness and death.        Ethanol mixes totally with water, which takes it everywhere in the body that water goes. The amount of alcohol that a person may drink varies with age, sex, weight and drinking history.       Heavy drinking can cause a healthy liver to become fatty and enlarged. Eventually scarring ( cirrhosis) can cause liver failure and death. Prolonged heavy drinking can eventually damage the muscle tissue of the heart. It may also lead to some long-term damage to brain. Alcohol is depressive drug and can be addictive. Drinking heavily on a particular occasion produces drunkenness, during which speech become slurred, vision is blurred and reaction times are slowed. Some cultures forbid its use.
