Zusammenfassung: | PURPOSE:The titled one-pack type composition, obtained by polymerizing a reactive unsaturated monomer and double bond-containing peroxy compound with a specific acrylate ester in respective ratios to give the peroxy groups present in the composition and having good cohesive force and adhesive properties. CONSTITUTION:An adhesive composition obtained by polymerizing (A) 100pts.wt. compound expressed by formula I (R1 is H or CH3; R2 is 1-18C alkyl), e.g. methyl acrylate, with (B) 0-29pts.wt. reactive unsaturated monomer, copoly merizable with the component (A) and having one or more hydroxyl groups, carboxyl groups, epoxy groups, amino groups and derivatives thereof and anhydrides, e.g. acrylic acid, and (C) 0.5-15pts.wt. compound expressed by formula II (R3 is H or 1-5C alkyl; R4 and R5 are 1-4C alkyl; R6 is H, 1-12C alkyl, etc.; n is an integer 0-4), e.g. tert-butylperoxy allyl carbonate, provided that the total amount of the components (B) and (C) is 0.5-30pts.wt. so as to give the peroxy groups in the component (C) present in the composition. |
