The present invention relates to a polymer delivery system for RNAi therapies that includes diseases where siRNA may be effective. In particular the invention relates to polymeric structures that self assemble into nano particles for siRNA delivery. Such polymers include a block copolymer comprising a cationic polymer capable of binding to siRNA, a p H mediator capable of disrupting endosomes and a polymer capable of binding with cell membrane thereby to release the block copolymer into the cytoplasm and wherein the cationic polymer is capable of degradation thereby to deliver siRNA.
