Herstellung hydroxylendstaendiger Polyester und von bei dieser Herstellung als Katalysator geeigneten Alkoxyden

A process for producing hydroxy-terminated polyester by polymerizing a lactone or a mixture of lactones in the presence of a catalyst having the general formula MM'(-OROH)4 where M is an alkali metal, M' is aluminum or boron and R is alkylene, isoalkylene, cycloalkylene or aralkylene. Poly...

description A process for producing hydroxy-terminated polyester by polymerizing a lactone or a mixture of lactones in the presence of a catalyst having the general formula MM'(-OROH)4 where M is an alkali metal, M' is aluminum or boron and R is alkylene, isoalkylene, cycloalkylene or aralkylene. Polyesters having the general formula 0 PARALLEL HO-R-O-10 C-R'-O- n-C-R''-OH are produced where R is a bifunctional hydrocarbon group, R' and R'' are alkylene groups and n is a whole number equal to or larger than 3.
