Moreover, the novel materials have shown good biocompatibility in both in vitro and in vivo (whole organism) experiments. In this regard, PDGAHex NPs were tested for their stability in different environments and for their ability to encode enhanced drug loading. MLV is a product that was designed as a viable replacement for lead sheeting which as we all know is a hazardous material and very difficult to work with. The (MLV for short) is a high grade vinyl that is filled with barium salts and silica which give it mass. This 2 lb Weight per square foot MLV carries an STC 32 rating. 169.99 Mass Loaded Vinyl is now the industry standard for soundproofing. It can be applied to walls, ceilings and doors. Interestingly, while the bare PDGA showed improved water solubility and diminished self-assembling ability, the Hex variation demonstrated enhanced features as a nanocarrier. Excellent for use in Building Walls, Studios, Traffic & Street Construction & More. Mass Loaded Vinyl is an excellent sound dampening material that is used for soundproofing. The properties of the novel poly(diglycerol adipate) (PDGA) variants have been compared against known polyglycerol-based polyesters. For the first time we have replaced glycerol with the more hydrophilic diglycerol, as well as adjusting the final amphiphilic balance of the polyester repetitive units by incorporating the more hydrophobic 1,6- n-hexanediol (Hex). We have investigated the effect of the variation of both hydrophilic and hydrophobic segments upon physical properties and drug interactions as well as self-assembly and NPs stability. To overcome this, in the present work, we applied a more significant variation of the polyester backbone while maintaining mild and sustainable polymerisation conditions. This leads to weak drug-polymer interactions and subsequent low drug-loading in NPs, as well as low NPs stability. Despite showing these advantages over commercial alkyl polyesters, PGA suffers from a series of key drawbacks caused by poor amphiphilic balance. Sustainably derived poly(glycerol adipate) (PGA) has been deemed to deliver all the desirable features expected in a polymeric scaffold for drug-delivery, including biodegradability, biocompatibility, self-assembly into nanoparticles (NPs) and a functionalisable pendant group.
