    摘要: A stain resistant no-mix orthodontic adhesive is disclosed. The adhesive comprises:(a) a first component having a relatively low viscosity and which contains an acrylic or methacrylic diester of ethoxylated bisphenol-A, an acrylic or methacrylic diester of an alkanediol, and benzyl acrylate or methacrylate; and(b) a second component containing a filler and an acrylic or methacrylic diester of ethoxylated bisphenol-A, an acrylic or methacrylic diester of an alkanediol, and benzyl methacrylate or acrylate, said filler being present in an amount within the range of from about 50 to about 80 weight percent of said second component,wherein, one of said first and second components contains a perioxide catalyst and the other of said components contains a tertiary amine activator for said peroxide catalyst.

    摘要: Compositions having high notched Izod impact strength and Gardner VHIT impact value are achieved by blending polyglutarimides, multiple stage polymers based on butadiene or acrylates, and polycarbonate in a weight ratio such that the polycarbonate comprises about 12 to 25% of the blend.
