Definitions
- the present invention relates to syndiotactic polypropylene onto which a functional monomer has been grafted.
- This product is useful as a compatibilizing agent, for example in blends of polyamide and polypropylene or in blends of polypropylene and glass fibers.
- Syndiotactic polypropylene is also useful as a coextrusion binder.
- the coextrusion binder consists of (i) either grafted syndiotactic polypropylene then optionally diluted in at least one polyolefin (C1) or in at least one polymer of elastomeric nature (D) or in a mixture of (C1) and (D) , (ii) either grafted isotactic polypropylene diluted in syndiotactic polypropylene and optionally in at least one polymer of elastomeric nature (D).
- coextrusion binders are useful, for example, for manufacturing multilayer materials for packaging. Mention may be made of the materials comprising a polyamide film (PA) and a polypropylene film (PP), the polypropylene film can be laminated on the polyamide film or coextrudes with the polyamide. The coextrusion binder is placed between the polypropylene and the polyamide for good adhesion of the PA and of the PP.
- PA polyamide film
- PP polypropylene film
- the coextrusion binder is placed between the polypropylene and the polyamide for good adhesion of the PA and of the PP.
- These multilayer materials can be three-layer structures PP / binder / EVOH in which EVOH denotes a copolymer of ethylene and vinyl alcohol or an ethylene vinyl acetate copolymer (EVA) saponified in whole or in part or structures five-layer PP / binder / EVOH / binder / PP.
- EVOH denotes a copolymer of ethylene and vinyl alcohol or an ethylene vinyl acetate copolymer (EVA) saponified in whole or in part or structures five-layer PP / binder / EVOH / binder / PP.
- Polypropylene is described in Kirk-Othmer, Encyclopedia of chemical technology, 4 th edition, Vol 17, pages 784-819, John Wiley & sons, 1996. Almost all of the polypropylene marketed consists essentially of isotactic polypropylene possibly containing a little atactic polypropylene. There are many prior arts describing grafted polypropylene but it is still isotactic polypropylene.
- US Pat. No. 5,235,149 describes packages closed by lids made of aluminum foil, a layer of binder and a layer of polypropylene.
- the binder layer of the cover consists of different polymers grafted with acrylic acid or maleic anhydride, the polymers can be chosen from polyethylene, polypropylene, copolymers of ethylene and vinyl acetate and copolymers of ethylene and methyl acrylate.
- Patent DE 19 535 915 A describes polypropylene graft copolymer block for bonding polypropylene films to metal sheets.
- EP 689 505 describes structures similar to those described in the previous patent but which are used to make food packaging.
- Patent EP 658,139 describes structures similar to those described in the previous patent but the binder is a random copolymer polypropylene grafted comprising from 1 to 10% of comonomer, the Mw / Mn ratio is between 2 and 10 and the MFI (Melt flow index or melt flow index) is between 1 and
- the radical grafting of functional monomers on the polyolefins is carried out either in the molten state, or in solution using radical initiators such as peroxides, or in the solid state by irradiation. Under the action of radicals, side reactions occur at the same time as the grafting reaction. They lead to an increase in molecular weight in the case where the polymer to be grafted is polyethylene, or to its decrease in the case where it is polypropylene. If the quantity of radicals necessary for the grafting reaction is large, the evolution of the molecular weight of the polyolefin leads to a significant modification of its viscosity in the molten state. These grafts are generally carried out in an extruder.
- the viscosity of the grafted polyethylene is so high that it can no longer be extruded; the viscosity of the grafted polypropylene is so low that it too can no longer be extruded.
- Patent EP 802207 describes the grafting of high quantities of functional monomer onto mixtures of polyethylene and polypropylene.
- the increase in the molecular weight of the polyethylene is compensated by the decrease in the molecular weight of the polypropylene present during the radical grafting reaction.
- Most often this mixture of polyethylene and co-grafted polypropylene is then diluted in a polyolefin.
- melt flow index also designated by MFI, abbreviation for Melt Flow Index
- the present invention relates to syndiotactic polypropylene onto which a functional monomer has been grafted.
- the invention also relates to a coextrusion binder consisting, (i) of grafted syndiotactic polypropylene then optionally diluted in at least one polyolefin (C1) or in at least one polymer of elastomeric character (D) or in a mixture of (C1) and (D), (ii) either grafted isotactic polypropylene diluted in syndiotactic polypropylene and optionally in at least one elastomeric polymer (D).
- a coextrusion binder consisting, (i) of grafted syndiotactic polypropylene then optionally diluted in at least one polyolefin (C1) or in at least one polymer of elastomeric character (D) or in a mixture of (C1) and (D), (ii) either grafted isotactic polypropylene diluted in syndiotactic polypropylene and optionally in at least one elastomeric polymer (
- the present invention also relates to a multilayer structure composed of a layer comprising the preceding binder, and directly attached thereto a layer of nitrogenous or oxygenated polar resin such as a layer (E) of a polyamide resin, of a saponified copolymer of ethylene and vinyl acetate, of a polyester resin, of a mineral oxide deposited on a polymer such as PE, polyethylene terephthalate or EVOH, or else a metallic or metalloplastic layer.
