| titleOfInvention | Foam-forming copolymers based on propylene, foamable granules and foam articles made from them |
| abstract | A foam-forming propylene-ethylene random copolymer is provided which is characterized in that DOLLAR A (1) its ethylene unit content [x (% by weight)] is between 0.2 and 10% by weight, DOLLAR A (2) its melt index [MI (at 230 ° C. under a load of 2160 g)] between 1 and 16 g / 10 min. DOLLAR A (3) its extraction content in boiling diethyl ether [E (% by weight)] and x satisfy the relationship of the formula (I): be DOLLAR AE 0.25 x + 1.1 DOLLAR A (4) Melting point [Tm (DEG C)], measured by differential scanning calometry, and x satisfy the relationship of the formula (II): DOLLAR A Tm 165 - 5 x DOLLAR A (5) the proportion of isotactic triads in the PPP chain portion, measured by · 13 · C-NMR, is not less than 98 mol%, and DOLLAR A (6) the relationship between the relaxation time Ð (sec) of the copolymer obtained by a frequency division measurement at a frequency omega¶0¶ = 10 · 0 · rad / sec, and the MI of the copolymer preferably satisfies the formula (III): DOLLAR A Ð 0.80-0.42 X log MI DOLLAR A is a foamable granulate and foam article. DOLLAR A The copolymer and the foamable granulate therefrom have improved primary and secondary foamability and the cellular articles (foam articles) made of the copolymer have excellent mechanical properties, including rigidity. |
