ABSTRACT
This chapter describes a variety of applications in which these novel properties play a role as well as a number of other potential applications inherent in the chemical or biological effects of the cyclic unit. Additional publications or patents on the use of poly(diallyldimethylammonium chloride) or related copolymers in the areas of electroconductive polymers and related subjects have appeared in the literature. Many have dealt with improving the surface resistivity and solvent holdout in conditioning paper for maximum electroconductive properties. The advantages for the cyclopolymers or the corresponding copolymers must arise from some property inherent in the cyclic structure and its effect on the polymer properties. Cyclobutene ring opening has been shown to be a useful reaction for the synthesis of well-defined double stranded molecules, including polymers. Cyclopolymers of phthaldehyde, first reported in 1967, have recently been shown to have potential as resists. However, other cyclopolymers or the corresponding copolymers have found potential uses in these industries.
