  • Patent number: 5189231
    Abstract: The filter plugging point and the pour-point at low temperatures of compositions based on liquid hydrocarbons from refining are improved by means of the addition, preferably in solution, of a mixture of an ethylene copolymer with another copolymerizable monomer and of an imidized acrylic polymer.
    Type: Grant
    Filed: April 29, 1991
    Date of Patent: February 23, 1993
    Assignee: Societa' Italiana Additivi Per Carburanti s.r.l.
    Inventors: Luciano Canova, Ettore Santoro, Luciano Bonoli, Paolo Falchi
  • Patent number: 5171330
    Abstract: The fluidity at low temperatures of compositions based on refinery liquid hydrocarbons can be improved by adding, preferably under solution, [l.sub.4 ]-methacyclophanes with substituents, obtained from the condensation reaction of a resorcin with a product containing an aldehyde group, followed by a reaction with halides of organic acids or alkyl halides.
    Type: Grant

  • Patent number: 5106919
    Abstract: Compatible mixtures of styrene copolymers of type SAN (AES, ABS, SAN) with polyglutarimides, characterized in that the polyglutarimides are prepared by imidization of poly(meth)acrylates and/or poly(meth)acrylic acid with amides of formulaX--Z--NHRwhereX=H, hydrocarbyl or, when ##STR1## a --NHR radical or a --Y--CO--NHR radical; R=aryl; ##STR2## --C.sub.6 H.sub.4 --SO.sub.2. The mixtures composed of SAN copolymers and N-aryl polyglutarimides having a Tg of at least 140.degree. C. are claimed as new mixtures.

  • Patent number: 5097084
    Abstract: The fluidity at low temperatures of compositions based on liquid hydrocarbons from refining is improved by the addition, preferably in solution, of ethylene/propylene/(conjugated diene) copolymers or terpolymers, containing 20-55% of propylene, optionally degraded by thermo-oxidation, and structurally characterized by values of at least one of X.sub.2 and X.sub.4 parameters, which are equal to, or lower than, about 0.02, indicative of the absence in the polymeric chain of propylene linking inversions.
