1. Mono-functional Linear PEGs

The mono-functional SUNBRIGHT® Series comprising highly purified methoxy PEG as the starting material hardly contains bif-unctional PEG derived from diol impurities. Accordingly, bridging reactions (sidereaction) which pose an obstacle to PEGylation can be completely prevented.
