  • Apparatus for the production of additive containing synthetic linear polymers
    Patent number: 4319848
    Abstract: A process for the production of synthetic linear polymers which contain atives is described, in which the polymer and the additives, both in the fluid state, are mixed, the resulting mixture is homogenized, and the homogenized mixture is in part conveyed to apparatus which uses it to make a product and in part is recycled, the recycled amount being preferably at least 5% of the total weight of the mixture. The preferred polymers are polyamides. The additives may be of any kind, e.g. antistatics, and they may be added as such or as a master batch consisting of a polymeric base containing finely particulated solid materials such as carbon black, matting agents or pigments.
    Type: Grant
    Filed: March 21, 1980
    Date of Patent: March 16, 1982
    Assignee: SNIA VISCOSA Societa Nazionale Industria Applicazioni Viscosa S.p.A.
    Inventors: Giorgio Lambertini, Gianfranco Sala
