  • Pressure sensitive adhesive with butene-1 copolymers
    Patent number: 9284475
    Abstract: Pressure sensitive adhesive composition and multilayer easy peel re-closable structures thereof, comprising a butene-1 (co)polymer (A) having a content of butene-1 derived units of 80 wt % or more; a flexural modulus (MEF) of 80 MPa or less; a melting temperature DSC (TmI) lower than 110° C., and optionally a tackifier (B).
    Type: Grant
    Filed: October 18, 2011
    Date of Patent: March 15, 2016
    Assignee: Basell Poliolefine Italia S.r.l.
    Inventors: Gianluca Musacchi, Inge Elisabeth Roucourt, Giampaolo Pellegatti, Johan De Clippeleir, Stefano Spataro
  • Soft polyolefin compositions with improved processability
    Patent number: 9029455
    Abstract: Soft polyolefin composition with improved processability comprising from 8 to 45% by weight of a polypropylene component (A), from 82 to 45% by weight of an elastomeric component (B), and from 10 to 25% by weight of a viscosity reducing agent (C) comprising polybutene-1 and paraffinic wax or grease. The composition is easily processable also by injection molding and has better tensile properties than compositions in which processability is improved by visbreaking.
