The synthesis methods of dendrimer-star polymers are introduced.

This paper studied a novel approach to hetero-arm star-shaped polymers of MMA and styrene by means of atom transfer radical polymerization.

0 polyamidoamine(PAMAM) dendrimers were modified to amphoteric dendritic polymers using acryloyloxyethyl trimethylammonium chloride(DAC),sodium acrylic acid(SAA) and 2-acrylamido-2-methylpropanesulfonic acid(AMPS) as modifiers of terminal groups by Michael addition reaction.

The progress of structural characteristics, synthetic methods and applications in pharmaceuticals such as enhancing drug solubility and bioavailability, controlling drug release, gene delivery system and pharmacological activity based on itself of dendrimers is reviewed.

0G)PAMAM)dendrimers were synthesized by means of divergent procedure.

A series of polyamide-amine(PAMAM)dendrimers were synthesized by divergence method.

This review about dendrimer(PAMAM included) focus on the new application in medicine.

The star-shaped polymer's cyclosiloxane core was synthesized by hydrosilylation with dimethyldichlorosilane and 2,4,6,8-tetravinyl-2,4,6,8-tetramethylcyclotetrasiloxane as raw materials,and characterized by infrared spectroscopy and nuclear magnetic resonance spectroscopy.

In this paper, 5,10,15,20-tetra(4-carboxylphenyl)porphyrin(TCPP) was synthesized first, then a kind of new star-shaped polymer was synthesized successfully with TCPP as the core and poly(butyl acrylate)(PBA) obtained by atom transfer radical polymerization(ATRP) as the arms.
