Acryloyl materials for molded plastics

A method for producing a siloxanyl monomer composition, the composition comprising monomers having the structures:

• wherein R1 represents a C1-C20 substituent having at least one unsaturated bond,
• wherein R3 represents a C1-C7 divalent substituent,
• wherein A represents a siloxanyl group, and
• wherein X represents a hydrogen;
• the method comprising the step of reacting unsaturated compounds having the structures:
• wherein R1 represents a C1-C20 substituent having at least one unsaturated bond,
• wherein R2 represents a C1-C7 substituent having at least one unsaturated bond, and
• wherein X represents a hydrogen;
• with a siloxanyl compound having a structure A-H, wherein A represents a siloxanyl group, in the presence of a metal catalyst,
• thereby producing a reaction mixture containing a siloxanyl monomer;
• wherein the molar ratio of the unsaturated compound to the siloxanyl compound is from about 1.2:1 to about 10:1 during the reacting step.
