PREPARATION OF DIESTERS OF (METH)ACRYLIC ACID FROM EPOXIDES

The application relates to a process for preparing a (meth)acrylic acid diester by reacting a (meth)acrylic acid anhydride with an epoxide in the presence of a catalyst system comprising a first and/or second catalyst in combination with a co-catalyst. The first catalyst is a halide of Mg or a trifluoromethanesulfonate of a rare earth element; the second catalyst is a Cr(lll) salt; and the co- catalyst is a tertiary amine, a quaternary ammonium salt, a tertiary phosphine or a quaternary phosphonium salt.

POLYESTER STEREOCOMPLEXES, COMPOSITIONS COMPRISING SAME, AND METHODS OF MAKING AND USING SAME

Compositions comprising stereocomplexes of enantiomeric polymer chains having individual repeat units formed from the reaction of an epoxide and cyclic anhydride. The compositions can be made by mixing two types of enantiomeric polymer chains having opposite absolute stereochemistry. The compositions can be used in applications such as biomedical applications and drug delivery applications.
