Use of specific low molecular weight .epsilon.-caprolactone homopolymers having an average molecular weight of about 1000 g/mol. Which give unexpected advantages as a plasticizer for vinylic polymer compositions. The plasticizers may be incorporated into vinylic polymer compositions, such as PVC compositions and give the vinylic polymer composition into which they are incorporated properties approximating those which contain traditional plasticizers, such as DOP, DOA and TOTM while avoiding various disadvantages associated therewith.
L'invention concerne l'utilisation d'homopolymères de .epsilon.-caprolactone de faible poids moléculaire spécifique dont le poids moléculaire moyen est d'environ 1000 g/mol, cette propriété conférant aux compositions polymères vinyliques des avantages inattendus liés aux plastifiants. Les plastifiants peuvent être incorporés dans des compositions polymères vinyliques, par exemple, dans celles à base de PVC; ils confèrent à la composition polymère vinylique dans laquelle ils sont incorporés des propriétés qui la rapprochent des compositions contenant des plastifiants traditionnels tels que DOP, DOA et TOTM tout en évitant les différents inconvénients associés à ces derniers.
