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 Chemical Intermediates

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 a chemical intermediate used to provide unique derivatives.  The new wax has lactide functionality that can be further reacted using common reactions known to the industry.  Reactions can include: transesterification with alcohols or acids, transesterification with other esters, crosslinking with trifunctional (or higher) alcohols or acids or esters, hydrolysis with water, amidation with amines, reduction with e.g., a hydride reducing agent or a Grignard reagent. 

In summary, BHI’s new line of polyethylene / polylactide block copolymers can be used as chemical intermediates to provide unique derivatives.  Benefits include, but are not limited to...
