Abstract : This invention is directed to a thermoplastic polymer that is solid at room temperature and which expands on further polymerization, to form a crosslinked polymer, and to a process for preparing the polymer and the crosslinked polymer. In a preferred embodiment tile polymer is prepared by polymerizing 10-90 but preferably 20-80 mole percent of a lower alkyl acrylic monomer containing a spirobislactone moiety, 10-90 but preferably 20-80 mole percent of a lower alkyl acrylic monomer containing an epoxide moiety, and 0.1-5 but preferably 0.5-1 mole percent of a lower alkyl acrylic monomer containing a functional moiety chosen from primary amino, secondary amino, mercaptan, and hydroxyl groups which can initiate crosslinking with the spirobislactone moiety. The crosslinked polymer is devoid of a spirobislactone carbonyl absorption band and is insoluble in conventional organic solvents.
