Abstract

An extrudable PVA-containing composition is disclosed, which enables PVA articles to be manufactured on conventional extrusion apparatus. The composition includes a lubricant, such as a fatty acid amide, most preferabl y octodecanamide and is most preferably formed into pellets by cold pressing. The compositions are suitable for manufacturing a variety of products.</SDOA B>

Claims (30)

1. A polymer feedstock in the form of a cold-pressed tablet or pellet for use in extrusion of an extruded product containing PVA, the cold-pressed tablet or pellet comprising a blend of PVA and up to 5% lubricant by weight to render the blend extrudable.
2. A polymer feedstock according to Claim 1 wherein the lubricant comprises a fatty acid amide.
3. A polymer feedstock according to Claim 2 wherein the fatty acid amide is a straight or branched C12-C24 fatty acid amide.
4. A polymer feedstock according to Claim 2 or 3 further comprising a plasticiser.
5. A polymer feedstock according to Claim 4 wherein the plasticiser is selected from ethylene glycol, glycerine, glycerol, triethylene glycol, low molecular weight polyethylene glycols and C2-C8 amides.
6. A polymer feedstock according to any of Claims 1 to 5 comprising up to 20%
plasticiser, by weight.
7. A polymer feedstock according to any preceding claim further comprising a filler.
8. A polymer feedstock according to Claim 7 wherein the filler comprises inert, inorganic material.
9. A polymer feedstock according to Claim 7 wherein the filler comprises a superabsorbent material.
10. A polymer feedstock according to Claim 8 or 9 wherein the filler comprises both an inert, inorganic material and superabsorbent material.
11. A polymer feedstock according to Claim 8, 9 or 10 wherein the inorganic filler comprises calcium carbonate.
12. A polymer feedstock according to any preceding claim comprising, by weight, up to 50% filler, up to 5% lubricant and up to 20% of a plasticizer.
13. A polymer feedstock according to Claim 12 comprising, by weight, 5-50%
filler, 0.5 to 2.5% lubricant, 5 to 15% plasticizer and 40-80% PVA.
14. A polymer feedstock according to any of Claim 1-13, further comprising an additional lubricant component to reduce adhesion of the polymer feedstock to surfaces.
15. A polymer feedstock according to Claim 14 wherein the additional lubricant comprises a stearate.
16. A PVA-containing polymer feedstock in the form of a cold-pressed tablet or pellet comprising, by weight:-40 to 80% PVA;
to 50% filler;
5 to 15% plasticizer; and 0.5 to 2.5% lubricant.

23. A method of making a PVA-containing polymer feedstock comprising blending PVA with a lubricant, said lubricant including a fatty acid amide in the presence of an amount of moisture sufficient to bind the polymer feedstock into tablets or pellets upon cold pressing and cold pressing the feedstock into tablets or pellets.
24. A method according to Claim 23 comprising blending, in a high speed blender, PVA with up to 5% by weight of lubricant.
25. A method according to any of Claims 22 to 24 comprising adding moisture to the components to be blended.
26. A method according to any of Claims 23 to 25 wherein PVA and lubricant are fed into a high speed mixer gravimetrically.
27. A method of making a PVA-containing polymer feedstock comprising blending PVA and a filler, wherein the filler comprises a superabsorbent material.
28. A method according to Claim 27 comprising blending PVA and a superabsorbent material in the presence of sufficient moisture to bind the polymer feedstock into tablets or pellets upon cold pressing.
29. A method of extruding a PVA-containing polymer feedstock comprising blending PVA and at least one of a lubricant and a filler to form a feedstock for an extrusion process, the feedstock being in the form of pellets or tablets, and extruding the feedstock into a product, wherein the feedstock is prepared substantially without melting of the PVA.
30. Use of a fatty acid amide in an amount of 0.5% to 1.5% by weight as an internal lubricant together with use of an external lubricant in an amount of 0.0001 to 0.1% by weight in the manufacture of a cold-pressed polymer feedstock containing PVA
and up to 50% filler wherein the feedstock is manufactured by cold pressing into pellets or tablets using residual moisture to bind the pellets or tables and substantially without melting of the PVA.
