WebPoly (methyl methacrylate) (PMMA) is a vinyl-based cationic polymer capable of condensing nucleic acids by ionic interactions. Nucleic acid condensation property of … WebPoly (ethyl methacrylate) ( PEMA) is a hydrophobic synthetic acrylate polymer. It has properties similar to the more common PMMA, however it produces less heat during polymerization, has a lower modulus of elasticity and an overall softer texture. [7] It may be vulcanized using lead oxide as a catalyst [8] and it can be softened using ethanol.

WebAnionic polymers: Anionic polymethacrylate polymers contain methacrylic acid functional groups, which dissociate and render the polymer soluble at the higher pH of the small intestine and colon.Anionic polymers containing methacrylic acid–ethyl acrylate copolymer (1:1) in coating products (eg, Eudragit® L 30-D or Kollicoat® MAE 30 DP) are soluble from … WebPolymethylmethacrylate Standards. Polymethylmethacrylate (PMMA) standards are extremely versatile as they can be used for organic GPC/SEC with a wide range of medium polarity eluents, such as tetrahydrofuran, toluene, methyl ethyl ketone, and ethyl acetate. They also work well with more polar organic eluents, for example dimethylformamide ...
