Polymethacrylate Derivatives

There is no doubt that CYTOP is by far the best available material for fabricating GI POFs. CYTOP-based GI POFs continue to break records for the 

V represents C-H vibrational absorptions of PMMA. The subscript number is the vibrational quantum number.

As the formation of LC phase in comb-like polymers is predetermined by the interaction of mesogenic groups, it would have seemed, that the temperature range of LC state for such systems should not depend on the length of the main chain, i.e. on the degree of polymerization (DP). However, studies 44,49) on the dependence of Tc] on DP carried out for some polyacrylic and polymethacrylic derivatives of cyanobiphenyl, as well as for polyparabiphenylacrylate 51 (Fig. 5), have shown that... 

The formation of the polymer complexes between polyMAEA and polyMAEU was studied under similar conditions as for polymethacrylate derivatives. PolyMAEA and polyMAEU form a stable 1 1 polymer complex in DMSO-EG. Hypodjromidty of the polymer system increased slowly, and equilibrium was attained after 7 days (hypochromidty 66%). Formation of the complex depends on temperature and type of solvent used, as in the case of polymethacrylate ... 

Modification of the drug structure by the covalent attachment of a water-solubilizing group through a biodegradable linker (e.g. poly(ethylene glycol) (PEG), poly(ethylene imine) (PEI), a water-soluble polymethacrylate derivative, a poly(amino acid) such as poly...

A wide range of polyacrylic acids (PAAs), polymethacrylic acids (PMAAs), polyacrylamides (PAMs), their salts and homo-, co-, and terpolymer derivatives are available from a great many manufacturers around the world today. Polyacrylates especially are a backbone of BW chemical formulations and are manufactured with an almost infinite variety of average molecular weights (MWs), MW distributions, activity strengths, and other characteristics. 

Poly methacrylates and copolymers of butadiene and methacrylate having /arious pyrimidine derivatives (Figures 1, and 2) were prepared by free radical polymerization of the methacrylate monomers (14-16). In the case of the poly(MAOT -alt-MAOT3Me )> the polymer was obtained by the reaction of the polymethacrylic anhydride with the hydroxyethyl... 

The photo-cross-linkability of a polymer depends not only on its chemical structure, but also on its molecular weight and the ordering of the polymer segments. Vinyl polymers, such as PE, PP, polystyrene, polyacrylates, and PVC, predominantly cross-link, whereas vinylidene polymers (polyisobutylene, poly-2-methylstyrene, polymethacrylates, and poly vinylidene chloride) tend to degrade. Likewise, polymers formed from diene monomers and linear condensation products, such as polyesters and polyamides, cross-link easily, whereas cellulose and cellulose derivatives degrade easily. ...
