NEW SYNTHETIC POLYMER

WHAT IS POLYMERISATION?

• Polymerization is a process of reacting monomer molecules together in a chemical reaction to form polymer chains or three-dimensional networks.

TYPES OF POLYMERS• There are two types of polymers; Addition polymers E.g.: polyethylene, polypropylene,

acrylic Condensation polymersE.g.: rayon, nylon

NEW SYNTHETIC POLYMER

• We have used the monomers of the polymers, nylon and polyester.

• Nylon -a tough, lightweight, elastic synthetic polymer with a protein-like chemical structure, able to be produced as filaments, sheets, or moulded objects.

• Polyester-a synthetic resin in which the polymer units are linked by ester groups, used chiefly to make synthetic textile fibres.

•We have named it Polyon.•We have chosen these fibers to get a good range of properties.

Properties of Polyon• Wrinkle resistant• Dries quickly• Variation of luster• High tenacity• Abrasion resistant• Retains shape• Light weight • Easy to handle• Resistant to insects, fungi,

midew.

WORD BANK• 1) LUSTER-Luster is the surface appearance of

a substance, or the manner in which it reflects light. A variation in the quantity of light reflected produces different degrees of intensity of luster; a variation in the nature of the reflecting surface produces different kinds of luster.

• 2) ABRASION RESISTANT- Abrasion resistance is the ability of a fabric to resist surface wear caused by flat rubbing contact with another material.

CONDENSATION POLYMERISATION

• Condensation polymerization, as a contrast, normally involves the generation of small molecule products, like water. For example, ethylene glycol reacts with terephathalate to form poly(ethylene terephathalate) polymer. Meanwhile, water is generated. It looks like two molecules "condense" with each other to form this polymer. These include polyester, polyamide and polycarbonate, nylon .

• CONDENSATION POLYMERIZATION WILL HAPPEN HERE BECAUSE BOTH NYLON AND POLEYESTER WE CHOOSE IS A CONDENSATION POLYMER.
