Embodiment 1
[0210] Example 1 Preparation of polyacrylate siloxane copolymer network composition I in water
[0211] Composition of 234.9g roughly into MD 85 D. * 2.2 D' 5.5 M(D * : from the reaction of Si-H with 4-vinylcyclohexene-1,2-epoxide; D": from the reaction of Si-H with allyl-terminated polyether CH 2 =CH-CH 2 -O-(EO) 24 (PO) 27 -CH 3 Hydrosilylated) organopolysiloxane was mixed with 29.5 g of acrylic acid. About 20 mg of 4-methoxyphenol and 0.8 g of tetraisopropyl titanate were added. The mixture was heated to 90°C for about 2 hours. 72 g of the resulting material was then mixed with 13.36 g of acrylic acid and 341 g of deionized water. Nitrogen was bubbled through for 30 minutes to remove oxygen from the system. Then 0.86 g of ascorbic acid and 2.58 g of hydrogen peroxide were added. The mixture was stirred for about 2 hours to give an opaque soft solid.
Embodiment 2
[0212] Example 2 Preparation of polyacrylate siloxane copolymer network composition II in silicone fluid
[0213] Roughly compose 400g into MD 125 DH 7.5 M's silane fluid (hydride fluid) with 12.15 g of 4-vinylcyclohexene-1,2-epoxide and 746.55 g of 2 =CH-CH 2 -O-(EO) 24 (PO) 27 -CH 3 Allyl-terminated polyether blends. Slow the reaction with sodium propionate. The mixture was heated to 85° C. and 0.7 ml of a platinum catalyst solution (10 mg / ml of chloroplatinic acid in ethanol) was added. The mixture was stirred at 90°C for 3 hours to form an epoxy functional polyether-polysiloxane copolymer. The resulting copolymer was neutralized with sodium bicarbonate, vacuum stripped, and filtered. 52.31 g of the resulting epoxy-functional polyether-polysiloxane copolymer and 1.24 g of acrylic acid were then mixed. About 10 mg of 4-methoxyphenol and 0.1 g of tetraisopropyl titanate were added. The mixture was heated to 90°C for about 2 hours. The mixture was then cooled to r...
Embodiment 3
[0214] Example 3 Preparation of polyacrylate siloxane copolymer network composition III in silicone liquid
[0215] Roughly make up 200g into MD 200 D. H 7.5 The silane solution of M with 5.99 g of 4-vinylcyclohexene-1,2-epoxide and 84.34 g of 2 =CH-CH 2 -O-(EO) 5 (PO) 5 -CH 3 Allyl-terminated polyether blends. Slow the reaction with sodium propionate. The mixture was heated to 85° C. and 0.1 ml of a platinum catalyst solution (10 mg / ml of chloroplatinic acid in ethanol) was added. The mixture was stirred at 80°C for 3 hours to form an epoxy functional polyether-polysiloxane copolymer. The resulting copolymer was neutralized with sodium bicarbonate, vacuum stripped, and filtered. 50.00 g of the resulting epoxy-functional polyether-polysiloxane copolymer was then mixed with 1.59 g of acrylic acid. About 10 mg of 4-methoxyphenol and 0.1 g of tetraisopropyl titanate were added. The mixture was heated to 90°C for about 2 hours. The mixture was then cooled to room t...
