Title:
【発明の名称】眼への使用に好適なシリコン含有ポリマー
Document Type and Number:
Japanese Patent JPH10509763
Kind Code:
A
Abstract:
Copolymers formed from dimethacrylates of polyalkylene glycols and vinylic reactive silicones having up to 20 silicon atoms in the substantial absence of additional cross-linking agents. The copolymers may include a hydrophilicity-modifying monomer. The preferred silicon is TRIS (i.e., 3-methacryloxypropyl tris(trimethylsiloxy) silane), while the preferred polyalkylene glycol is polypropylene glycol dimethacrylate. The copolymers are especially suited to use in the fabrication of soft contact lenses because of the good durability and high oxygen permeability and transmissibility. Oxygen transmissibilities of greater than 70 barrers/mm are preferred.
