A polymer useful as a solid support for a variety of applications is provided. The polymer is prepared from a composition comprising at least one type of olefinic monomer and a multifunctional (meth)acrylate crosslinker of the following formula (I): ##STR1## wherein: (a) R.sup.1, R.sup.2, and R.sup.3 are each independently hydrogen or a methyl group;(b) R.sup.4 is hydrogen or an organic group or substituent that can interact in the polymerization and/or crosslinking process or is nonreactive under the conditions of the polymerization and/or crosslinkling process;(c ) R.sup.7, R.sup.8, and R.sup.9 are each independently --CH.sub.2 --CH.sub.2 --, --CH.sub.2 --CH.sub.2 --CH.sub.2, --CH.sub.2 --CH(CH.sub.3)--, or --CH(CH.sub.3)--CH.sub.2 --;(d) each of 1, m, and n is no greater than about 100 with the proviso that at least one of 1, m, or n is at least 1.
