Iso-Butyl methacrylate

Park et al. [20] reported on the synthesis of poly-(chloroprene-co-isobutyl methacrylate) and its compati-bilizing effect in immiscible polychloroprene-poly(iso-butyl methacrylate) blends. A copolymer of chloroprene rubber (CR) and isobutyl methacrylate (iBMA) poly[CP-Co-(BMA)] and a graft copolymer of iBMA and poly-chloroprene [poly(CR-g-iBMA)] were prepared for comparison. Blends of CR and PiBMA are prepared by the solution casting technique using THF as the solvent. The morphology and glass-transition temperature behavior indicated that the blend is an immiscible one. It was found that both the copolymers can improve the miscibility, but the efficiency is higher in poly(CR-Co-iBMA) than in poly(CR-g-iBMA),...

During the synthesis reactions molecular weights (Mn) of the polystyrene and poly(iso-butyl) methacrylate) blocks were kept constant at 40,000 and 10,000 g/mole respectively.

Another interesting example belonging to the same general principle was described by Graham (56). On one hand he prepared an amine terminated polystyrene (sodium amide initiation in liquid ammonia) and showed that it contained only one terminal primary amine group per polymer chain. On the other hand copolymers were prepared by free-radical initiated solution copolymerization of small amounts of /S-iso-cyanatoethyl methacrylate with several other monomers as methyl, butyl and lauryl methacrylates, acrylonitrile and styrene.

Satturwar et al (2007) prepared block copolymers of PEG and t-butyl methacrylate, iso-BA, n-BA or propyl methacrylate by ATRP. They obtained pH-sensitive micelles by hydrolysis of t-butyl groups. The poorly water-soluble drug candersartan cilexetil (CDN) was incorporated in the micelles, and the in vitro drug release as a function of pH was studied. The entrapment efficiency of CDN was found to be above 90%. The release of CDN from pH-sensitive micelles increased with increase in pH from 1.2 to 7.2. Thus, this block copolymer synthesized by ATRP can form micelles which exhibit high loading capacities of CDN and release of drug in a pH-dependent response.
