Polymer Chemistry Online A-Z. This polymer chemistry online book has been part of CROW's polymer database since 2016. The objective of this online book is to provide an introduction to polymer chemistry. The hyperbranched structure of the jellyfish-like superplasticizer was achieved by anionic ring opening polymerization of glycidol using a partially deprotonated bis-glycidolized Jeffamine as initiator. Thus, a diblock copolymer was obtained, composed of one linear polyetheramine side chain and a hyperbranched polyglycerol moiety.

The mixed solutions were stirred for 12 h at 318 K. The suspension mixture of carboxylic MWNTs in meth-anol was added to the mixed solutions, and then the final suspension mixture was stirred for 5 h at room temperature. The excess JEFFAMINE M-2070 was re-moved in the dialysis tubing (3.5 k MWCO) for ...
