Polymers based on acrylic acid have gained considerable importance in recent years. Their essential chemistry is discussed in section 10.8.2 on synthetic thickeners. Copolymers of acrylic acid with acrylonitrile and methyl acrylate (10.68) contain a random distribution of cyano, ester and acidic sidechain groups [169].

Pipet 0.5 pL of sample to the sample plate. Preferable concentration lpmol -pL Mix the sample and matrix2 by drawing in and out of the pipette. Allow to air dry and acquire spectra. aFor peptides, small proteins, and most other compounds a sat. soln of 2-cyano-3-(4-hydro-xyphenyl)acrylic acid in 0.1% TFA in H20/MeCN (1 1) is used. This matrix requires about half the laser energy of other matrices.

In the benzo[g]indolizine series, the ester (756) has been obtained from the isoquinolium ylide (755 R = C02Et) and cyclopentanone (which is a synthetic equivalent of cyclopentyne), acetic anhydride reacts with the ylide to afford the acetoxy-derivative (757), and the action of keten on the cyano-analogue (755 R = CN) leads to the ketone (758)/ Diphenylcyclopropenone combines with 1-methyl-3,4-dihydroisoquinoline to form the rearranged adduct (759). The benzo[e]indolizine (761) is one of the products of the thermolysis of the azide (760). Heating indoline with acrylic acid in polyphosphoric acid gives a mixture of the tri- and tetra-cyclic compounds (762) and (763). ...

There are many polymers that are suitable for the production of nanoparticles employed for drug delivery, which can generally be divided into two groups natural polymers, e.g., polysaccharides (chitosan), proteins (albumin, gelatin), as well as synthetic polymers, e.g., polyesters (poly(lactic add), poly(glycolic add), poly(hydroxy butyrate), poly-e-caprolactone, poly-p-malic add, poly(dioxanones)) polyanhydrides (poly(adipic add)) polyamides (poly(amino acids)) phosphorous-based polymers (polyphosphate) poly(cyano acrylates) polyurethanes polyortho esters and polyacetals. Extreme attention has to be paid to the biodegradability and biocompatibility of the polymers. It is essential that polymers used for medical applications are not detrimental for the tissue or cells and that they can be easily decomposed into simple harmless molecules and eliminated by the human body [ 18-22]. 

UV absorbers (Figure 5.20) are organic compounds that absorb harmful UV light and dissipate the absorbed energy as harmless thermal energy. Important classes of UV absorbers are 2-hydro-xybenzophenones, benzotriazoles, hydroxyphenyl-s-triazines, and oxalanilides. Some other compounds such as hydroxyphenylpyrimi-dines, salicylic acid derivatives and cyano acrylates are also useful. 

The fabricated devices based on N719 and 2-cyano-3-(4-(diphen-ylamino) phenyl) acrylic acid sensitizers with modified electrolyte show the efficiency of 7.33% and 2.63% at an irradiation of AM 1.5, and 37% and 22% energy conversion efficiency increments, respectively. 

Kawakami and Sonoda reported on a similar system in 1993 [72]. They used PVK as photoconductive polymer and TNF as a sensitizer, too. The system also included a plasticizer and the non-linear optical dye 1 -cyano-2(4-dimethylaminophenyl) acrylic acid. Unfortunately, the 40-50 pm layers prepared by blade casting showed diffraction maximum efficiency of which was only 4 X lO . Furthermore fading of colour in the irradiated areas was observed. It was concluded that the monomeric dye migrates within the polymer and reacts photochemically. 

The poly alkyl acrylates and poly cyano acrylates generally resist biodegradation. In soil-burial tests, weight loss has been reported for copolymers of ethylene and propylene with acrylic acid, acrylonitrile, and acrylamide. The rapidly polymerizable systems such as poly(alkyl-2-cyanoacrylate)s adhered to moist surfaces have been examined in biomedical applications. Poly(methyl-2-cyanoacrylate) is the most degradable among the alkyl esters, and its degradability decreases as alkyl size increases (Holland etal., 1990).
