| description | The present invention relates to processes for forming random prepolymers comprising comprising at least one (meth)acrylate component and at least one (meth)acrylamide. More specifically, the present invention relates to processes comprising providing a first reaction mixture comprising at least one (meth)acrylate component having a first reaction rate constant, k1; adding to said first reaction mixture, under reaction conditions comprising a reaction time, at least one (meth)acrylamide component having a second reaction rate constant k2 which is less than about 0.5 k1, wherein at least one of said (meth)acrylate component and said (meth)acrylamide component comprise silicone and at least one of said (meth)acrylate component and said (meth)acrylamide component comprise at least one hydrophilic component; and said at least one (meth)acrylamide component is added gradually over a reaction time and under prepolymer reaction conditions to form a prepolymer. |
