Description

       

  Procédé pour influencer les phénomènes de polymérisation ainsi que les propriétés des produits obtenus.

  
Au brevet principal, on a décrit un procédé pour fabriquer des polymériaats de haute valeur à partir d'esters organiques et inorganiques de l'aloool vinylique par polymérisation en présence de crotonate de vinyle. Lors ' du traitement ultérieur, on a trouTé maintenant qu'on peut obtenir à partir d'esters de vinyle et d'une addition de crotonate de vinyle des produits d'un genre nouveau particulièrement désirés au point de vue technique, en polymérisant un mélange des deux esters de vinyle en l'absenoe de solvants à l'aide de combinaisons peroxydées on présenoe

binaison peroxydée, outre le peroxyde de benzoyle, l'ester peraoétique tel qu'il est obtenu par oxydation d'aoétaldéhyde à faible teneur en cobalt par de l'oxygène moléculaire à environ 0[deg.] convient surtout très bien. Grâce à une addl-tion de crotonate allant jusqu'à quelques pourcents, on  obtient des produits exempts de bulles, limpides comme  du Terre, coriaces à température ordinaire, apte à résis- 

  
ter à un choc ou à un coup, et qui peuvent par exemple  être employés comme Terre organique.

Exemple 1.-

Le mélange est déjà, après quelques heures, pris en une gelée transparente . Elle duroit graduellement, après quoi elle est enlevée du vase de verre cylindrique. , l'air, la masse devient après un court repos si dure qu'elle ne peut être marquée par l'ongle. Elle est très coriace et apte à résister en toute circonstance aux coups et auxohocs. Par réchauffage à haute température par

Exemple 2.

  
Un mélange de 91 parties en poids d'acétate de vinyle et 4 parties de orotonate de vinyle est polymérisé avec 5 parties de la solution du perester mentionnée plus haut, à 50 - 60[deg.]. On obtient un polymérisat dur et transparent.

Exemple 3.-

  Process for influencing the polymerization phenomena as well as the properties of the products obtained.

  
The main patent discloses a process for making high value polymeric compounds from organic and inorganic esters of vinyl alcohol by polymerization in the presence of vinyl crotonate. In further processing, it has now been found that, from vinyl esters and addition of vinyl crotonate, novel products which are particularly desired from a technical point of view can be obtained by polymerizing a mixture. of the two vinyl esters in the absence of solvents using peroxidized combinations are presented

  
 <EMI ID = 1.1>

  
In addition to benzoyl peroxide, peroxidized bison, the peraoetic ester as obtained by oxidation of low-cobalt aoetaldehyde with molecular oxygen at approximately 0 [deg.] is particularly suitable. Thanks to an addition of crotonate of up to a few percent, one obtains products free of bubbles, limpid like Earth, tough at ordinary temperature, able to resist.

  
ter to a shock or a blow, and which can for example be used as organic Earth.

Example 1.-

  
A mixture of 91 parts by weight of acetate

  
vinyl and 2 parts vinyl crotonate is added to

  
 <EMI ID = 2.1>

  
The mixture is already, after a few hours, taken into a transparent jelly. It gradually lasted, after which it was removed from the cylindrical glass vessel. , air, the lump becomes after a short rest so hard that it cannot be marked by the nail. It is very tough and able to withstand knocks and shocks in all circumstances. By reheating at high temperature by

  
 <EMI ID = 3.1>

Example 2.

  
A mixture of 91 parts by weight of vinyl acetate and 4 parts of vinyl orotonate is polymerized with 5 parts of the perester solution mentioned above, at 50-60 [deg.]. A hard and transparent polymerizate is obtained.

Example 3.-

  
'A mixture of 91 parts by weight of vinyl acetate and 2 parts of vinyl crotonate is polymerized with 0.5 part of benzoyl peroxide with simultaneous addition

 <EMI ID = 5.1>

  
in the example above. This product is also very tough. without aoetaldehyde, it was not possible to obtain products as homogeneous, so clear and at the same time so hard.
