Abstract
On prépare du polypropylène de poids moléculaire réglé en mesurant moment par moment la quantité de chaleur évacuée, en calculant moment par moment le volume d'hydrogène à consommer sur base de la chaleur évacuée et on peut obtenir le volume X d'hydrogène consommé par quantité unitaire de polypropylène (en déterminant X à partir de l'équation : 1 n n = 1 n X + A entre les viscosités intrinséques n de polypropylènes et les volumes d'hydrogène consommé par volumes unitaires de polypropylènes et en introduisant ensuite de l'hydrogène dans le récipient de réaction en volumes correspondant aux variations du volume calculé.
