the crosslinkable group comprises a core unit substituted with at least one crosslinkable unit of formula (I):

##STR00001##

the crosslinkable group is bound to the polymer or is a crosslinkable compound mixed with the polymer;

Ar is aryl or heteroaryl which may be unsubstituted or substituted with one or more substituents independently selected from monovalent substituents and a divalent linking group linking the unit of formula (I) to the core unit; and

R is independently in each occurrence H, a monovalent substituent or a divalent linking group linking the unit of formula (I) to the core unit, with the proviso that at least one R is not H.

A polymer compound comprising a constitutional unit having a group represented by the formula (1):

##STR00001##

wherein Ring A.sup.1A and Ring R.sup.2A represent an aromatic hydrocarbon ring or a heterocyclic ring and these rings each optionally have a substituent, nA represents an integer of 0 to 5, nB represents an integer of 1 to 5, L.sup.A and L.sup.B represent an alkylene group, a cycloalkylene group, an arylene group, a divalent heterocyclic ring group, a group represented by NR, an oxygen atom or a sulfur atom, and R represents a hydrogen atom, an alkyl group or the like, and Q.sup.1 represents a crosslinkable group.

Arylclobutene-containing multi-functional monomers are useful in the preparation of arylcyclobutene-based polymer coatings. Compositions comprising one or more arylclobutene-containing multi-functional monomers and one or more oligomers comprising as polymerized units one or more arylcyclobutene monomer provide arylcyclobutene-based polymer coatings having reduced stress. Such compositions are useful in the manufacture of electronic devices.
