Synthesis of photo and thermosetting monomers and polymers based on benzocyclobutene

2-(Bicyclo[4.2.0]octa-1,3,5-trien-3-yl)-adamantan-2-ol

“…values of glass transition temperatures (that is relatively low for linear, non-crosslinked adamantane polymers) and high thermal stability [5][6][7].…”

“…The combination of benzocyclobutene and adamantane in a monomer or polymer seems attractive because a benzocyclobutene ring opens when heated above 200 • C and gives an active isomer (o-xylylene) that provides crosslinking of the polymer. BCB crosslinked polymers have high values of glass transition temperatures (that is relatively low for linear, non-crosslinked adamantane polymers) and high thermal stability [5][6][7].…”

Di(bicyclo[4.2.0]octa-1(6),2,4-trien-3-yl)dimethylsilane

“…Organosilicon resins with benzocyclobutene (BCB) filler have been demonstrated to be promising as low-dielectric-constant (low-k) materials for the electronics industry and related applications. These materials are currently being actively studied [1][2][3][4][5][6].…”

Bicyclo[4.2.0]octa-1,3,5-trien-3-yl-dimethyl((E)-styryl)-silane

“…Dow chemicals (www.dow.com) presents a line of composite materials (CYCLOTENE™) with divinylsiloxane (DVS) and benzocyclobutene (BCB) based component as photoresists and thermosets (Divinyl siloxane bis-benzocyclobutene, DVS-BCB). In recent years, many new articles have appeared devoted to the development of hybrid silanes or siloxanes and BCB containing monomers [5][6][7][8][9][10]. The polymerization of these compounds occurs due to the presence of acrylate, silocyclobutene groups, alkenes (including vinyl, styryl, and allyl groups), etc.…”
