Two corn. acrylic resins were polymerized at 18-55 degrees C in casts optionally under elevated pressure (2 bar) for 10 or 30 min, joined together by using the same acrylic resin at 37 degrees C for 24 h and studied for bending strength in a 3-point test (500 N, 2.0 mm/min). The samples joined at elevated temperature and under increased pressure showed higher mech. strength.
