Adhesive for bonding dissimilar materials in medical device

A method of bonding dissimilar materials of medical device components, the method comprising:

• applying an adhesive on a surface of one medical component comprised of a non-polar, non-polyvinyl chloride thermoplastic polymeric material or on a surface of another medical component comprised of a polyacrylate, polyacrylonitrile, polyester, and/or a polycarbonate or on both such surfaces;
• contacting the surfaces;
• exposing the contacted surfaces to heat or light radiation to crosslink the adhesive and to bond the surfaces;
• and
• subjecting the bonded surfaces to sterilization;
• wherein the adhesive formulation consisting essentially of:
• (a) a polyolefin oligomer having reactive acrylate groups and alkenyl groups, (b) an initiator, and (c) a solvent, and
• wherein the polyolefin oligomer having reactive acrylate groups comprises a polybutadiene oligomer having reactive acrylate groups represented by Formula (I):
• wherein R1 represents an acrylate or methacrylate moiety linked to the polyolefin chain through urethane linkages, n is an integer from 10 to about 500, and m is an integer from 0 to about 250.
