Study Of Polymers Based On Cardanol

Cardanol is principal component of Cashew Nut Shell Liquid (CNSL) used as raw material. According to its structure characteristic, a series of high-performance or functional polymers have been prepared by organic synthesis and polymeric synthesis. Then the polymers' structure and properties have been analysed by physico-chemical measures and modern test means.By oxidation of double bond in the side chain of cardanol , epoxy- cardanol polymer has been systhesized , which may interact with polyamine to form arnino-cardanol polymer. It is founded that ammo- cardanol polymer can cure with epoxy resin and coordinate heavy ions into amino- cardanol metal coordinated polymers, amino- cardanol copper (II) coordinated polymer, which is obtained by the reaction of amino- cardanol polymer with CuCl2 , is reactive for catalytic-initiating the polymerization of olefinic monomers such as methyl methacrylate (MMA) and butyl methacrylate (BMA).Condensation polymers from cardanol, formaldehyde and amine (PCX) are systhesized by copolycondensation, then are reacted with epoxy resin to form coating films. The films remain properties of both cardanol-formaldehyde resin and epoxy resin , which are acid-resisting, alkali-resisting and organic solvent-tolerant, and also have good service time. Besides, utilizing coordinative action of the polymers' diverse functional group as -OH, -NH- or -NH2 etc, PCX will widely be used in dealing in waste water contained heavy metal ions.Copolymers of cardanol and formaldehyde as well as coordinated polymers based on these copolymers and metal compounds, all are high-performance or functional polymers. Cardanol formaldehyde ferric polymer (PC-Fe), cardanol n-butanal ferric polymer (PB-Fe) and cardanol furfural ferric polymer (PF-Fe) are studied by IR, HPLC, TG and physico-chemical measures etc. The results show that the forming of PX-Fe are owed to the coordination between phenolic hydroxy and Fe3+ and further cross-link reaction of polymers. PC-Fe possesses the excellent general characteristic, especially resistance to heat and solvents. Furthermore, PC-Fe may effectively catalyze esterification. PC-Fe microsphere, which has porous structure, is prepared by suspension condensation. It has proved that PF-Fe microphere has good properties of absorbing heavy metal ions and polyamide.
