Definitions
- the present invention relates to the preparation of polyolefin-based adhesives. More particularly, the invention relates to a method for preparing polyolefin-based adhesives that have improved clarity and adhesion in multilayer polyolefin films.
- Polyolefin-based adhesives are useful for bonding polyolefins with polar materials such as nylon, ethylene vinyl alcohol copolymer (EVOH), and metals.
- Polyolefin-based adhesives commonly comprise maleic anhydride-grafted polyolefins.
- the grafting is usually performed by visbreaking, with or without free radical initiator, the polyolefin in the presence of maleic anhydride to cause formation of free radicals on the polymer chains that react with maleic anhydride.
- the grafted polyolefin is typically let-down with additional polyolefin resins to a desired concentration and to provide a polyolefin-based adhesive. See U.S. Pat. No. 4,487,885.
- the grafted polyolefin can be let-down by a variety of polyolefin resins, including high density polyethylene (HDPE), low density polyethylene (LDPE), linear low density polyethylene (LLDPE), polypropylene, and ethylene-vinyl acetate copolymers.
- High performance adhesives also utilize a polyolefin elastomer as a let-down resin.
- the elastomer is premixed with other letdown resins and the mixture is then blended with the grafted polyolefin.
- the grafted polyolefin, elastomer and other let-down resins are simultaneously blended.
- the invention is a process for making a polyolefin-based adhesive.
- the adhesive comprises a maleated polyolefin, a polyolefin elastomer, and a linear low density polyethylene.
- the process comprises blending the maleated polyolefin, in sequence, with the polyolefin elastomer and then with the linear low density polyethylene.

- the maleated polyolefin is first blended with the polyolefin elastomer; and the resultant mixture is then blended with LLDPE.
- the blending can be performed by any suitable methods. Preferably, the blending is performed thermally at a temperature above the melting points of the components. For instance, the blending can be performed in a Banbury mixer or in an extruder. Extrusion is more preferred for commercial production. Twin-screw extruders, such as those marketed by Coperion under the designations ZSK-53 and ZSK-83, ZSK-90, and ZSK-92 are particularly preferred.
- the polyolefin-based adhesive produced shows significantly improved clarity and adhesion compared with those made by blending the maleated polyolefin with a premixed polyolefin elastomer and LLDPE.
- the process of the invention integrates grafting maleic anhydride onto a polyolefin, blending the maleated polyolefin with a polyolefin elastomer, and then blending the resulted mixture with LLDPE. More preferably, all these three steps are performed in a multistage extruder.
- Multistage extruders are known. For instance, U.S. Pat. Appl. Pub. No. 2006/0076705 teaches a multistage extruder assembly.
- the grafting reaction is preferably in the presence of a free radical initiator.
- Suitable free radical initiator includes 1 ,1- bis(tert-butylperoxy)cyclohexane; n-butyl-4,4-bis(tert-butylperoxyvalerate);
- the free radical initiator is preferably added to the extruder after maleic anhydride and the polyolefin have been thoroughly mixed. After the grafting reaction is essentially completed, the maleated polyolefin moves to the second stage of the extrusion where a polyolefin elastomer is fed to the extruder and blended with the maleated polyolefin. After the maleated polyolefin and elastomer are thoroughly mixed, the mixture moves to the third stage of the extrusion where LLDPE is fed to the extruder and blended therewith.
- the process of the invention is integrated with the LLDPE production.
- This is a so-called "in-line” process.
- a maleated polyolefin is blended with a polyolefin elastomer and the resultant mixture is then blended with an LLDPE reactor powder from the LLDPE polymerization line before peptization.
- the invention also includes a multilayer polyolefin film which comprises a tie-adhesive layer made according to the process of the invention.
- multilayer we mean that the film have at least two more layers besides the tie-adhesive layer.
- the tie-adhesive layer bonds the other layers together.
- One example of multilayer film is a five-layer film which has the structure of HDPE/tie-layer/EVOH/tie- layer/HDPE. Ethylene-vinyl alcohol copolymer (EVOH) layer is employed as a barrier to oxygen.
- Another example of multilayer film is a seven-layer film which has the structure of LLDPE/HDPE/tie-layer/EVOH/tie-layer/HDPE/LLDPE.
- the multilayer film of the invention can be made by a variety of processes.
- the multilayer film can be made by co-extrusion, coating, and other laminating processes.
- the film can be made by casting, blown film, or double-bubble orientation processes.
- Blown film processes include high-stalk and in-pocket processes.
- the extrudate exits the annular opening in the die in the form of a tubular "stalk" that is inflated a distance (usually the length of the stalk) from the extrusion die.
- the tube is inflated as the tube exits the extrusion die. After the tube is flattened and cooled, it can be slit to form a film.
- HDPE is Alathon ® M6210, product of Equistar Chemicals, LP, which has an MI 2 of 0.95 dg/min and density of 0.958 g/cm 3 .

- Example 1 The general procedure of Example 1 is followed, but the adhesive resin is made by blending the maleated HDPE with a pre-mixture of EPR and LLDPE.
- the adhesion is 1.4 Ib/in; for a 5-mil film, the adhesion is 2.6.
