The present invention describes method of preparation of esters or amides of lactyl lactates of general formula (I), where Z denotes to group of R-O or RR-N and R represent alkyl, aryl or H from lactide and the lactide is in contact with a hydrocarbyl alcohol and a hydrolyzable halide in a non-chlorinated organic solvent, or an amine initiated by a hydrolysable halide or hydrogen halide solution or an ammonium hydrohalide, wherein the hydrocarbyl alcohol or amine is either aliphatic or aromatic and containing 1 to 1000 carbon atoms, preferably 1 up to 150 carbon atoms, and optionally one or more, preferably 1 to 5, -CH2- groups may be replaced by -O-groups.
The present invention provides compositions and methods relating to polylactides which may be used for drug delivery (e.g., parenteral delivery), wherein an organic solvent is not required.

Provided are an alicyclic structure-containing compound, a (meth)acrylate, and a method for producing the ester. The compound and the ester are useful as a monomer and the like for a photoresist used in semiconductor manufacturing and excellent in solubility, compatibility, defect reduction, roughness improvement, and the like, realized by using an alicyclic structure-containing compound containing a linking group having an ester bond and/or a linking group having an ether bond, a (meth)acrylate derived from the alicyclic structure-containing compound, and a method for producing the ester.

The invention is to provide a novel polyhydroxyalkanoate having a reactive function group within the molecule and a producing method therefor In a polyhydroxyalkanoate containing a unit having a vinyl group in a side chain, such vinyl group is utilized for deriving a polyhydroxyalkanoate comprising a carboxyl group or a unit having an amide group and a sulfonic acid group.
The present invention provides compositions and methods relating to polylactides which may be used for drug delivery (e.g., parenteral delivery), wherein an organic solvent is not required.
