Abstract
The invention relates to reactive monomers containing 2-cyanopenta-2,4-dienoate and methacrylic or acrylic double bonds in their molecules. The reactive monomers are easily polymerizable in a variety of ways. The polymerized reactive monomers can form strong adhesive bonds between a variety of substrates. The adhesive bonds are water and humidity resistant, heat resistant, impact and peel resistant and can sustain large loads and stresses. The polymerized reactive monomers are applicable as structural and industrial adhesives, medical and surgical adhesives and optical fiber coatings, and can be used in the manufacture of positive or negative photo or electron beam resists.
