Abstract
A curable composition containing at least one ethylenically unsaturated compound and at least one liquid elastomer is provided. The curable composition is useful for preparing a cold seal adhesive. A method is provided for preparing the cold seal adhesive, which includes the use of electron beam radiation to initiate polymerization of the curable composition.
Claims10
A process for preparing a cold seal adhesive comprising the steps of:
- a) providing a curable composition comprising:
- i) from 30 to 90 weight % of at least one ethylenically unsaturated compound selected from the group consisting of ethylenically unsaturated monomers and ethylenically unsaturated oligomers;
- ii) from 10 to 50 weight % of at least one liquid elastomer;
- and
- iii) from 0 to 60 weight % of at least one tackifier;
- wherein all weight % are based on total weight of said curable composition;
- and
- b) subjecting said curable composition to electron beam radiation to provide said cold seal adhesive.
