Abstract

The present invention relates to compositions which include compounds that are end-capped with silanes containing radiation cure groups. In addition, the invention relates to a method for preparing such compounds. In particular, the radiation cure groups are attached to the silane via a methylene linkage. Illustrative of the inventive compositions are those which include a compound of Formula (I):

Claims

2. The composition of claim 1, wherein

R² is a member selected from the group consisting of C₁ to C₄ alkyl and phenyl;

R³ is a member selected from the group consisting of methyl and phenyl; and

R⁴ is a member selected from the group consisting of methyl and phenyl.

3. The composition of claim 1, further comprising a filler.

4. The composition of claim 1, further comprising a radiation cure catalyst.

5. The reaction product of the composition of claim 4 upon exposure to radiation.

6. A method for making a composition, the method comprising the steps of mixing:

a) a siloxane of Formula (II);

7. The method of claim 6, wherein the mixing occurs in the presence of a basic component.

8. A composition comprising the reaction product of:

a) a siloxane of Formula (II);

9. A method of using a composition comprising a compound of Formula (I):
