Definitions
- the present invention relates to new uses of unmodified polypropylenes and grafted polypropylenes, and more generally of unmodified polyolefins and grafted polyolefins. Since their existence, unmodified polypropylenes, and more generally unmodified polyolefins, have been appreciated for their advantageous properties combined with their low cost. Thus, to date, they are used, in preference to any other plastic, in particular for tubes, films, sheets, hollow bodies and various parts of self-propelled vehicles such as fuel tanks. However, it has often happened that the level of mechanical properties reached by unmodified polypropylenes, and more generally by unmodified polyolefins, did not reach the level required for the intended applications.
- the mechanical properties in question relate in particular to the mechanical behavior at low speed (elastic modulus in tension, elongation at break, etc.), the mechanical behavior at high speed (resilience and / or maximum force on the test of the falling weight instrumented,. ..), the operating temperature range (softening temperature in the Nicat test, ...) and the evolution of the mechanical behavior of the material over time (creep test, ).
- Properties such as adhesion to a support (which depends critically on the chemical nature of the support) or dispersibility in a dispersion liquid are not mechanical properties within the meaning of the present invention.
- patent application GB 1 335 791 in the name of EASTMAN KODAK describes mixtures of unmodified polyproylene and polypropylene grafted with maleic anhydride, which have a level of tensile strength intermediate between that of non-polypropylene modified and that of grafted polypropylene (see Tables 3 and 6) or, at best, equivalent to that of unmodified polypropylene (as illustrated in Table 1).
- the mechanical properties requirements could not be met, that is to say that the grafted polyproylenes (and, more generally, the grafted polyolefins) behaved less well, for the mechanical properties in question, than their non-homologous counterparts.
- a first aspect of the present invention therefore relates to the use of at least one unmodified polyolefin [polyolefin (PI)] as an additive to a polyolefin composition (C2) comprising at least one polyolefin modified by grafting with acid and / or anhydride groups, optionally neutralized in whole or in part by at least one neutralizing agent [polyolefin (P2)], to improve the level of at least one mechanical property of the polyolefin composition (C2), up to a level improved both compared to that of the mechanical property of the polyolefin composition (C2) as compared to that of the mechanical property of a polyolefin composition (Cl) obtained by replacing weight for weight in the polyolefin composition (C2) all of the modified polyolefin (P2 ) with unmodified polyolefin (PI).
- PI unmodified polyolefin
- the weight ratio q w2 of the polyolefin (P2) and of the polyolefin composition (C2) [(P2): (C2)], before the addition of the polyolefin (PI), is advantageously greater than 0.50, preferably greater than 0.90, particularly preferably greater than 0.99 and very particularly preferably greater than 0.995; it can then either be composed of the polyolefin (P2), or be composed of the polyolefin (P2) and of less than 0.5% of the usual ingredients of the polyolefin compositions such as thermal stabilizing agents and antioxidant agents.
- a second aspect of the present invention relates to the use of at least one polyolefin modified by grafting with acid and / or anhydride groups, optionally neutralized in whole or in part by at least one neutralizing agent [polyolefin (P2)] as as an additive to a polyolefin composition (Cl) comprising at least one unmodified polyolefin (polyolefin (PI)), to improve the level of at least one mechanical property of the polyolefin composition (Cl), up to an improved level as compared to that of the mechanical property of the polyolefinic composition (Cl) as compared to that of the mechanical property of a polyolefinic composition (C2) obtained by replacing weight for weight in the polyolefinic composition (Cl) all of the unmodified polyolefin (PI) by modified polyolefin (P2).
- P2 neutralizing agent
- the weight ratio q w ⁇ of the polyolefin (PI) and of the polyolefin composition (Cl) [(PI): (Cl)], before the addition of the polyolefin (P2), is advantageously greater than 0.50, of preferably greater than 0.90, particularly preferably greater than 0.99 and most preferably greater than 0.995; it can then either be composed of the polyolefin (PI) or be composed of the polyolefin (PI) and less than 0.5% of the usual ingredients of the polyolefin compositions such as thermal stabilizers and antioxidants.
