    摘要： 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), wherein
    A1 is a divalent bonding group containing at least one heteroatom; and
    R1 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.
