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 Candle 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 additives to improve the oil binding and fragrance retention.  The new copolymer can modify the crystal structure of the candle to allow better retention of oil and high fragrance loadings.  The new copolymer can be used at levels up to 5% by weight in the candle.

·         As additives to improve the opacity of candles.  The new copolymer can modify the crystal structure to improve opacity, which can yield a better appearance for customers.  The new copolymer can be used at levels up to 5% by weight in the candle.

·         As additives to improve the appearance of candles.  The new copolymer can minimize surface flaws, bubbles, and cracks.  The new copoly...
