Free radical copolymerization and cross-linking copolymerization of the 4-chloromethyl styrene (CMS) with styrene (in various mole ratios), were carried out using α,α-azobis(isobutyronitrile) AIBN as initiator and 1,4divinylbenzene (DVB) as a crosslinking agent at 70 oC. The antimicrobial 4-hydroxybenzoic acid (4-HBA) was covalently attached to the obtained copolymers with replacement of all the chlorine atoms in CMS units. The copolymers, obtained in quantitative yields, were characterized by…

TLDR
P pH-sensitive systems could be useful for preparation of a muccoadhesive system and controlled release of N-(4-hydroxyphenyl)-2-( 4-methoxyphenol) acetamide in SGF and SIF and drug release studies showed that the increasing content of MAA in the copolymer enhances hydrolysis in SIF.

TLDR
The results have shown that polyvinyl chioroacetate is an appropriate carrier for release of the drug in human conditions and is potentially useful as polymeric prodrugs.
