Abstract:

Rheology modification of an ethylene/α-olefin interpolymer is achieved by blending the interpolymer with at least one branched polyolefin. The polyolefins can be homopolymers or interpolymers and have a branching index of less than 1. The ethylene/α-olefin interpolymer is a block copolymer having at least a hard block and at least a soft block. The soft block comprises a higher amount of comonomers than the hard block. The block interpolymer has a number of unique characteristics disclosed here. Rheology-modified ethylene/α-olefin interpolymer, i. e. , the resulting polymer blends, can be extruded or molded into many useful articles, such as films, sheets, profiles, gaskets, foams, etc.

C08F 210/00, C08J 9/00, C08G 85/00

US Classification:

521144, 521 50, 526 72

Abstract:

A polymer composition comprises at least an ethylene/α-olefin interpolymer and at least one other polymer. The other polymer can be selected from a second ethylene/α-olefin interpolymer, an elastomer, a polyolefin, a polar polymer, and an ethylene/carboxylic acid interpolymer or ionomer thereof. The ethylene/α-olefin interpolymer is a block copolymer having at least a hard block and at least a soft block. The soft block comprises a higher amount of comonomers than the hard block. The block interpolymer has a number of unique characteristics disclosed here. Also provided are gaskets, bottle cap liners, and closures that comprise or obtained from a compositon comprising at least one ethylene/α-olefin interpolymer and at least one polyolefin. The gaskets are capable of compression sealing various containers, without contaminating the contents. Liquid containers particularly benefit from the use of the novel gasket materials disclosed herein.

Thin Foamed Polyethylene Sheets

US Patent:

2008013, Jun 12, 2008

Filed:

Jun 30, 2004

Appl. No.:

10/560732

Inventors:

Felipe Martinez - Houston TX, US

International Classification:

B32B 27/32, C08J 9/00

US Classification:

428220, 521134

Abstract:

The present invention relates to the use of particular blends of LLDPE and LDPE together with specific fabrication conditions to make foamed sheets of thin gauge with MD tear properties similar to an equivalent gauge non-foamed sheet of the same composition. In particular, blends which combine a high MI LLDPE rich fraction with a low MI branched LDPE minor fraction provide the adequate balance of mechanical strength of the polymer base with its melt strength, extensibility and stress relaxation, allowing a thin foam film with MD tear strength which is comparable to non foamed counterparts of similar gauge and composition. The foamed films of the present invention are thin (generally from about 1 to 10 mils thick), and have an MD tear strength of at least about 160 grams for a 3 mil film as measured by ASTM D 1922. The foamed films of the present invention are preferably made at least in part from blends which comprise from 10 to 95 percent by weight of LLDPE having a relatively high (1.5 to 6) MI and from 5 to 90 percent of an LDPE resin having a relatively low MI (0.5 to 2.0).
