Abstract
This invention relates to vinylbenzyl and crosslinking bis-(vinylbenzyl) monomers for use in the preparation of polymers, especially ion exchange resins, and to methods for the preparation of the monomers and polymers. It is particularly concerned with the preparation, polymerization, and use of new nitrogenous monomers as crosslinking agents and/or function-introducing agents.
Claims4
A crosslinking and/or function-introducing bis-(vinylbenzyl) amine monomer represented by the formula ##STR1## wherein:
- R.sup.1 is a C.sub.1-16 alkyl, aryl, or aralkyl radical or a hydrogen radical;
- R.sup.2, r.sup.3 and R.sup.4 independently represent C.sub.1-16 saturated or unsaturated hydrocarbyl, halogen, nitro, hydroxy, alkoxy, amino, or hydrogen radicals;
- n is 1 or 2 wherein, if n is 2, each R.sup.1 is independently selected;
- X is an anion;
- and
- m is 0 or 1 when n is 1 and 2, respectively.
