  Resin \Res"in\ (r[e^]z"[i^]n), n. [F. r['e]sine, L. resina; cf.
     Gr. "rhti`nh Cf. {Rosin}.]
     Any one of a class of yellowish brown solid inflammable
     substances, of vegetable origin, which are nonconductors of
     electricity, have a vitreous fracture, and are soluble in
     ether, alcohol, and essential oils, but not in water;


     specif., pine resin (see {Rosin}).
     [1913 Webster]
  
     Note: Resins exude from trees in combination with essential
           oils, gums, etc., and in a liquid or semiliquid state.
           They are composed of carbon, hydrogen, and oxygen, and
           they consist primarily of polymerized small molecules
           having carboxylic groups. Copal, mastic, guaiacum, and
           colophony or pine resin, are some of them. When mixed
           with gum, they form the gum resins, like asafetida and
           gamboge; mixed with essential oils, they form balsams,
           or oleoresins. They are also used in making varnishes.
           [1913 Webster]
  
     2. Any of various polymeric substance resembling the natural
        resins[1], prepared synthetically; -- they are used,
        especially in particulate form, in research and industry
        for their property of specifically absorbing or adsorbing
        substances of particular types; they are especially useful
        in separation processes such as chromatography; as, an
        ion-exchange {resin}.
        [PJC]
  
     {Highgate resin} (Min.), a fossil resin resembling copal,
        occuring in blue clay at Highgate, near London.
  
     {Resin bush} (Bot.), a low composite shrub ({Euryops
        speciosissimus}) of South Africa, having smooth pinnately
        parted leaves and abounding in resin.
        [1913 Webster]
