2- Hydroxyethyl methylmethacrylate

Poly(2-hydroxyethyl methylmethacrylate) (PHEMA) has been used as a matrix for the detection of metal ions. 79 A near-IR dye (2,3-naphthalocyanine-tetrasulphonic acid) was immobilized in a polymer matrix which was attached to the reaction phase of two optical fibers. A mixture of the matrix and the dye was prepared by mixing PHEMA and dye in a 60/40 ratio. The optimum ratio of polymer and dye were not fully investigated. The dye/polymer mixture was applied to the tip of the probe in 10-to 15-/iL aliquots forming a thin coating on the probe after solvent evaporation as shown in Figure 7.9.

Materials. All monomers used for synthesis were free of inhibitors and freshly distilled 2-hydroxyethyl methacrylate (HEMA) dimethyl-acrylamide (DMA) N-vinylpyrrolidone (NPV) methylmethacrylate (MMA) 2-ethylhexylacrylate (EHA) isopropylmethacrylate (IPMA) n-butyl-acrylate (BA) ethyleneglycol-dimethacrylate (EGDMA) dimethacrylate macromer obtained by reaction of 1 mol polytetramethylene oxide diol (MW 2000) with 2 mol 2,4,4-trimethyl-l,6-diisocyanatohexane and 2 mol HEMA (PX). ... 

A membrane-controlled drug delivery device was developed to release tetracycline at zero-order rates. The tetracycline delivery vehicle Is a trllamlnate disk consisting of core and coating membranes fabricated from a series of 2-hydroxyethyl-methacrylate and methylmethacrylate copolymers. Appropriate adjustment of the monomer composition ratio Imparts a hydrophobic nature to the copolymer outer coating membrane (relative to the...

For this reason, copolymers 286 and 287 having a polar polymer structure were prepared by radical copolymerization of monomer 283 with methylmethacrylate or 2-hydroxyethyl methaciylate in presence of AIBN (Scheme 114). Indeed, these polymers seemed to be more compatible with the liquid reaction medium because both yield and enantioselectivity were higher widi the two NMO/acetone/H20 and K3Fe(CN)e/i-Bu0H/H20 systems in the AD of trans methyl cinnamate.
