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&#xb0; C., and optionally a tackifier (B).

Pressure sensitive adhesive with butene-1 copolymers

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.

Soft polyolefin compositions with improved processability

Soft polyolefin composition with improved processability comprising from 8 to 45% by weight of a polypropylene component (A), from 45 to 82% by weight of a polyolefin component (B), and from 5 to 25% by weight of a butene-1 (co)polymer (C) having a flexural modulus of 60 MPa or less.
