Abstract

The present invention relates to radiation or radiation/moisture dual curable polymers and methods for their manufacture. These polymers are useful for various applications in the fields of adhesives, coatings, and sealants. The radiation curable polymers comprise at least one terminal group of the general formula (I) -A¹-C(=O)-CR¹=CH₂ (I),whereinA¹ is a divalent bonding group containing at least one heteroatom; andR¹ is selected from H and C₁-C₄ alkyl, preferably H and methyl;wherein the polymer backbone is selected from the group consisting of polyoxyalkylenes, poly(meth)acrylates, polyesters, and combinations thereof.and optionally further comprise at least one terminal group of the general formula (II) -A²-SiXYZ (II),wherein X, Y, Z are, independently of one another, selected from the group consisting of a hydroxyl group and C₁ to C₈ alkyl, C₁ to C₈ alkoxy, and C₁ to C₈ acyloxy groups, wherein X, Y, Z are substituents directly bound with the Si atom or the two of the substituents X, Y, Z form a ring together with the Si atom to which they are bound, and at least one of the substituents X, Y, Z is selected from the group consisting of a hydroxyl group, C₁ to C₈ alkoxy and C₁ to C₈ acyloxy groups; and A² is a divalent bonding group containing at least one heteroatom.
