Abstract:
A crystalline copolymer of propylene with at least one olefin having the formula CH2&boxH;CHR,wherein R is an alkyl radical having from 2 to 10 carbon atoms, the content of said olefin in the crystalline copolymer of propylene being from 2 to 10 mole %, said crystalline copolymer of propylene having a melting point of from 110Â° C. to 140Â° C., said crystalline copolymer of propylene having a solubility in xylene at 25Â° C. lower than 10% by weight, and said crystalline copolymer of propylene having a distribution of said olefin such that no consecutive olefin sequences are detectable through 13C-N.M.R. analysis.
