[0109] Synthesis Example 1-1 (Polymer A-1; MPC0.50-SMA0.05-DMAA0.45)

[0110] 31.75g ​​of MPC (manufactured by NOF Corporation), 3.64g of stearate methacrylate (SMA, manufactured by NOF Corporation) and 9.60g of N,N-dimethylacrylamide (DMAA, Xingren company) was dissolved in 55.0 g of ethanol, put into a four-necked flask, and blown with nitrogen for 30 minutes. Then, 0.10 g of a product name "PERBUTYL ND" (manufactured by NOF Corporation) (hereinafter abbreviated as PB-ND) was added at 50° C., and a polymerization reaction was performed for 8 hours. The polymerization solution was dripped into 3 liters of diethyl ether while stirring, and the precipitated precipitate was filtered and vacuum-dried at room temperature for 48 hours to obtain 40.2 g of powder. The molecular weight evaluated by GPC was a weight average molecular weight of 1,000,000. Let this be polymer A-1. The data of IR, NMR, and elemental analysis are shown below.

Abstract

Provided are a contact lens care preparation capable of imparting durable surface lubricity and amebic adhesion inhibitory effect to a contact lens surface through a simple treatment, and a contact lens packaging solution utilizing the same. The contact lens care preparation is composed of a solution containing 0.01 to 2 weight/volume% of a polymer having particular monomer units with a phosphorylcholine-like group, particular (meth) acrylamide derivative units, and particular monomer units with a hydrophobic group at a particular ratio, and a weight average molecular weight of 5,000 to 2,000,000, and is useful as a contact lens packaging solution.

Description

technical field [0001] The present invention relates to a contact lens care preparation capable of imparting durable surface lubrication to the surface of a contact lens by simple treatment, and a packaging solution used when sealing a contact lens in a container Sex and the effect of inhibiting the attachment of amoeba. Background technique [0002] In recent years, for the purpose of improving the wearing feeling of soft contact lenses, attempts have been made to include polymer substances that improve surface lubricity in care formulations or packaging solutions for the soft contact lenses. However, the conventionally proposed improvement using a polymer material is insufficient in durability, and the wearing feeling deteriorates especially when worn all day, so improvement is being sought. [0003] Commercially available lens care preparations used for storage of soft contact lenses generally have a disinfecting ability in order to prevent the proliferation of bacteria ...
