Patent

CA 2155685

Thermoplastic polymer compositions are disclosed which comprise the following components: (A) 1 to 99% by weight of an amorphous propylene polymer hav- ing the following characteristics: - [?] > 1 dl/g, - % of syndiotactic dyads (r) - % of isotactic dyads (m) > 0, - less than 2% of the CH2 groups contained in (CH2)n sequences wherein n 2, - Bernoullianity index = 1 0.2; and (B) 1 to 99% by weight of a propylene polymer having an essentially syndiotactic structure, optionally containing from 0.1 to 30% by moles of units deriving from .alpha.-olefins of formula CH2=CHR in which R is an hydrogen atom or an alkyl group having from 2 to 10 carbon atoms. The compositions of the invention are endowed with good elasto-mechanical properties and are suitable for the produc- tion of low-temperature-heat-sealing films.
