A couple easy questions related to polymers

  1. Mar 3, 2010 #1
    1. HIPS is a :
    a)Polystyrene-Polybutadiene blend
    b)High Impact Polybutadiene Blend
    c)Polystyrene-Polybutadiene copolymer blended with polystyrene and polybutadiene
    d)High polystyrene matrix material

    I'm pretty sure it's not B, and I'm leaning towards C, but I'm not very confident

    2. A copolymer that is created with many large groups of like mers attached to each other would be best called a ______________ copolymer.

    I'm not sure on this at all but i think it's "block"

    please only answer if you're positive, because i want to makesure i understand all this
