TL;DR: In this paper, a novel experimental method has been devised to measure the swelling force developed during the exposure of thin polymeric discs to a swelling agent, which is applied for the determination of the swelling forces developed during water absorption of various systems including copolymers of 2-hydroxyethyl methacrylate or methyl methACrylate with methacrylic acid or acrylic acid.

TL;DR: Smart biomaterials composed of pH responsive polymers, poly((meth)acrylic acid), were synthesized using a precipitation polymerization technique and have the necessary physicochemical properties to serve as mucoadhesive controlled release drug carriers for the oral delivery of drugs.

TL;DR: In this paper, a thermally initiated free radical precipitation polymerization in ethyl acetate was investigated, and the structure and morphology of the microparticles were evaluated using Fourier transform infrared spectroscopy and scanning electron microscopy.

TL;DR: In this paper, both porous and non-porous polyvinyl alcohol (PVA) hydrogels were used as carriers to release proteins, and the number of freezing/thawing cycles affected the initial rate of release, the amount of protein released and the transport mechanism of BSA.
