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 Encapsulants

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 encapsulants or components of encapsulants for encapsulation of organic and inorganic particles.  The organic and inorganic particles can be pigments, dyes, fragrances, flavorings, or other additives.  The new wax enables good dispersion of the active material within the wax.  The encapsulated active material can improve handling characteristics, improve stability during storage and use, and provide more efficient use of the active materials.  The new wax can be used at levels up to 95% of the encapsulant by weight.

In summary, BHI’s new line of polyethylene / polylactide block copolymers can be used as encapsulants or components of encapsulants for en...
