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 Ink 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 pigment dispersants for organic or inorganic pigments.  The new wax can be used to improve the dispersion of pigments into inks.  The combination of polyethylene and polylactide blocks helps wet the pigments and enable better color development and improved loading. The new wax can be used at levels up to 35% by weight on the pigment.

·         As a component of hot melt ink formulations.  The new wax can be used to provide dimensional stability to the solid ink formulation.  The combination of polyethylene and polylactide blocks can improve the stability of the formulation while molten, and improve the adhesion of the ink to the substrate.  The new wax can...
