A polyester blend is made in a reaction of a linear polylactide resin and a thermoplastic epoxy group-containing polymer. The polyester blend is blended with a polyester having a glass transition temperature below 0C to form a polyester blend that is particular useful for making paperboard coatings in a melt extrusion process.

Polylactic resin compositions for paperboard coating and paperboard coating processes using the compositions

Polylactide resins are branched by reaction with a mixture of a polyene compound and a cyclic peroxide. This branching method produces a product that has a very high polydispersity, a high branching number (B) and excellent melt strength, without forming large amounts of gelled material. The branched polylactide resins are useful in many melt processing operations, in particular sheet and film extrusion, extrusion foaming, extrusion coating and fiber processing. They are characterized by easy processing and allow for broadened processing windows.

Hyperbranched polylactide resin compositions

2-Acetoxyalkanoic acid esters are made in a reaction of a 3,6-dialkyl-1,4-dioxane-2,5-dione or a poly(&#x3b1;-hydroxyalkanoic acid), an acetate ester and an alcohol or phenol in the presence of a transesterification catalyst. Unlike previous methods for making 2-acetoxyalkanoic acid esters, this process proceeds in high yield and high selectivity to the desired product.

Process for making esters of 2-acetoxyalkanoic acids using a 3,6-dialkyl-1,4-dioxane-2,5-dione or poly-(alpha-hydroxyalkanoic acid) as a starting material

2-Acetoxyalkanoic acid esters are made in a reaction of an &#x3b1;-hydroxyalkanoic acid ester and an acetate ester in the presence of a transesterification catalyst. Unlike previous methods for making 2-acetoxyalkanoic acid esters, this process proceeds in high yield and high selectivity to the desired product.
