Activité initiale

Rappel

Que signifie n ?

Qu’est-ce qu’il faut  pour obtenir les polymères ?

Rappel

N signifie le nombre de monomère. Pour obtenir les polymères, il faut associer plusieurs monomères.

Motivation

Qu’est ce qui fait que l’association de polymère forme les polymères ?

Motivation

Suite à un mécanisme qu’on appelle polymérisation.

Analyse

L A POLYMERISATION

  1. Définition

La polymérisation est un mécanisme d’obtention des polymères.

  1. Types

Nous avons 2 types de la polymérisation qui sont :

 - La polymérisation d’addition

 - La polymérisation de concentration

1°) La polymérisation d’addition

C’est simple addition de monomères.

Ces monomères sont toujours des molécules instaurés

c.à.d. elles possèdent une double ou triple liaison ; C=C et

C=C qui peuvent s’ouvrir.

Ex : E2 + CH2 = - x – CH2 – CH2 – X.

Le nombre de fois de monomère est déterminé par n.

X2 + n (CH2=CH2) – X-CH2-CH2)-X

n : nombre de fois monomère.

2°) La polymérisation de condensation ou polymérisation

C’est une réaction de monomère qui se fait avec

élimination d’une petite molécule comme d’eau.

Ex : - Polyamide (-CH2-C=0, NH-C=0-CH2)n.

       - Polyesters (-CH2-C0-0-CH2)n.

Synthèse

Qu’entendez-vous par la polymérisation ?

La polymérisation est un mécanisme d’obtention des polymères.
