“…The advantages of polymeric controlled-release pesticide formulations include (i) stabilization against environmental degradation by heat, air, humidity or microorganisms, (ii) decreased dosage, evaporation and leaching which in turn reduce environmental pollution, (iii) ease of handling of harmful crop protecting agents, reduced irritation of the human mucous-membrane and lower phyto-toxicity, (iv) lowering the mobility of the biocides in the soil and reducing their residues in the food chain and (v) longer application intervals. [1][2][3][4][5][6][7][8] There are mainly two broad categories, physical and chemical combinations, in polymer based controlled release formulations. In physical combinations the active agent is either encapsulated or heterogeneously dispersed or dissolved in the polymeric material.…”

A number of pesticide monomers containing pentachlorophenol as active group attached to vinyl groups, through oxyethylene as spacer group, have been prepared. The resulting monomers were homopolymerized under free-radical conditions and also copolymerized with styrene and 2-(2-hydroxyeth0xy)ethyl methacry late to introduce hydrophobic and hydrophilic nature to the resulting polymers. In addition, crosslinked copolymers were prepared by using different ratios of divinylbenzene.Data on the pentachlorophenol released through hydrolysis show that the degree of crosslinking, the hydrophilicity and the spacer group, as determined by the chemical structure and the polymer composition, as well as the pH, time and temperature appear to be major factors governing the rate at which a given polymer undergoes hydrolysis.

Synthetic organic polymers have gained great importance as supports and separation materials in biochemical laboratory techniques, medical diagnostics and biotechnological procedures. Furthermore they are used as carriers for drugs and biologically active substances in pharmacy, medicine and agriculture. Classifying their biocompatibility it has to be distinguished between in vitro application of polymers interacting on the one hand with molecular biosystems such as proteins and on the other hand with living cells, and in vivo administration in higher organisms, especially in the human organism.
