Highly cross-linked polymeric supports

A method of preparing a crosslinked polymer comprising:

• (a) combining an olefin-containing monomer and a multifunctional (meth)acrylate crosslinker in a solvent, wherein the multifunctional (meth)acrylate crosslinker has the following formula (I):
• ##STR5## wherein:
• (i) R.sup.1, R.sup.2, and R.sup.3 are each independently hydrogen or a methyl group;
• (ii) 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 crosslinking process;
• (iii) 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 --;
• and
• (iv) each of 1, m, and n is no greater than about 100 with the proviso that at least one of l, m, or n is at least 1;
• and
• (b) exposing the mixture to conditions to effect polymerization.

A method of synthesizing an organic molecule on a solid polymeric support comprising:

• (a) providing a solid polymeric support prepared from a composition comprising a multifunctional (meth)acrylate crosslinker of the following formula (I):
• ##STR6## wherein:
• (i) R.sup.1, R.sup.2, and R.sup.3 are each independently hydrogen or a methyl group;
• (ii) 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 crosslinking process;
• (iii) R.sup.7, RW, and R.sup.9 are each independently --CH.sub.2 --CH.sub.2 --, --CH.sub.2 --CH.sub.2 --CH.sub.2 --, --CH,--CH(CH.sub.3)--, or --CH(CH.sub.3)--CH.sub.2 --;
• and
• (iv) each of 1, m, and n is no greater than about 100 with the proviso that at least one of l, m, or n is at least 1;
• and
• (b) attaching an organic group to the solid polymeric support at the functional group site.
