Abstract

Baker Hughes Incorporated (BHI) announces a new line of polyethylene / polylactide block copolymers. These copolymers are produced via controlled polymerization to yield products with varying amounts of polyethylene and polylactide blocks. The process allows independent control of the polyethylene and polylactide blocks, which allows a wide range of properties. The polyethylene portion can have varied amounts of branching, ranging from essentially no branches (totally linear) to highly branched (hyperbranched). The polylactide content comes from biobased lactic acid and provides improved biodegradability for the new product. The polylactide content can range from <5% by weight up to around 95% by weight.

Polyethylene /Polylactide Block Copolymers for Textile Applications

Baker Hughes Incorporated (BHI) announces a new line of polyethylene / polylactide block copolymers.  These copolymers are produced via controlled polymerization to yield products with varying amounts of polyethylene and polylactide blocks.  The process allows independent control of the polyethylene and polylactide blocks, which allows a wide range of properties.  The polyethylene portion can have varied amounts of branching, ranging from essentially no branches (totally linear) to highly branched (hyperbranched).  The polylactide content comes from biobased lactic acid and provides improved biodegradability for the new product.  The polylactide content can range from <5% by weight up to around 95% by weight.

BHI claims the following application benefits:

·         As components of coatings used as thread lubricants.  The new wax can be used as components of coatings to apply to fibers and fabrics that provide lubricity during processing steps such as spooling, cutting, or sewing.  The coatings can minimize equipment wear and defects during processing.  The new wax can be used at levels up to 5% by weight on the fiber or fabric.

·         As components of coatings used to provide water resistance.  The new wax can be used as components of coatings applied to fibers and fabrics to provide water resistance.  The new waxes have good flexibility and adhesion to the fibers or fabrics, and help prevent water absorption. ...
