Liquid disinfectant compositions are disclosed which can be used to surface-coat substrates with polymeric films which are adherent, water-resistant and which can impart prolonged germicidal properties to the treated surfaces.

Disinfectant polymeric coatings for hard surfaces

A method of recovering oil floating on a water surface which has been contaminated with the oil by distributing upon the contaminated surface discrete particles of a hydrophobic macroporous highly crosslinked polymer. The particles are allowed to adsorb and to become laden with the oil. The oil laden particles are recovered from the water surface, and the oil from the oil laden particles is removed by applying compressive forces to the oil laden particles. Particles which are substantially free of the oil are recirculated and re-distributed upon the contaminated surface, and this sequence of steps is repeated until substantially all of the oil has been recovered.

Method of recovering oil from the surface of water

A process of decontaminating a surface contaminated with a toxic chemical agent in which there is applied to the contaminated surface, a macroporous cross-linked hydrophobic copolymer containing an agent which is a decontaminant for the toxic chemical agent present on the surface. The decontaminant can be a chemical neutralizer such as sodium hydroxide; lithium hydroxide; concentrated bleach; and mixtures of diethylene triamine, 2-methoxy ethanol, and sodium hydroxide, for example.

Decontamination of toxic chemical agents

This invention relates to a process of cleaning a surface soiled with a staining agent. The method includes the steps of applying to the soiled surface a highly cross-linked macroporous hydrophobic copolymer which contains a chemical entrapped therein which is a solvent for the staining agent present on the soiled surface, dissolving the staining agent with the solvent, absorbing the staining agent into the solvent entrapped copolymer, and removing the copolymer containing the solvent and the dissolved staining agent from the surface.

Method of cleaning surfaces

An aqueous cleaning dispersion, especially suitable as a contact lens cleaning solution, which includes a homogeneous mixture of water and a liquid-adsorbable powder homopolymer of tetraethylene glycol dimethacrylate.

Aqueous cleaning dispersions using adsorptive polymeric powder and

A method of forming a highly adsorptive polymer, which includes the steps of: (a) homogeneously mixing a solution of a monomer consisting exclusively of one or more types of polyunsaturated monomer, a monomer solvent, and an initiator, (b) polymerizing the monomers to form a polymer, wherein the monomer solvent is a solvent for the monomers and a non-swelling non-solvent for the polymer, and (c) removing the solvent from the polymer to form a dry powder.

Method of making highly absorptive polymers

A precipitation polymerization process for the production of a macroporous cross-linked copolymer in which there is added to a reactor equipped with a stirrer, at least one monounsaturated monomer and at least one polyunsaturated monomer, dissolving an inorganic polymerization reaction initiator in a homogeneous minimum-boiling binary azeotrope including a solvent and water, and conducting the polymerization in the azeotrope.

Method of making highly adsorptive copolymers

A process for preparing hydrophilic polymeric beads by suspension polymerization of one or more hydrophilic monomers and a cross-linking monomer in the presence of a free radical initiator and a regenerator amine at a temperature between 15.degree. and 35.degree. C. The beads are useful as abrasives in various cleaning compositions.

Process for preparing polymeric beads

This invention relates to solid compositions wherein a non-cosmetic functional material is entrapped in the lattice of the cross-linked polymer during in situ polymerization of the monomers forming the polymer lattice. The invention provides for conversion of solid and/or liquid products into solid, free-flowing forms by entrapment of the functional materials in a hydrophobic polymer lattice.

Lattice-entrapped composition

Inclusion of carbonyl modified amino acid monomers in polymeric compositions for biomedical applications, including contact lenses, increases the water content and oxygen permeability of the polymer without significant changes in other desirable properties of the polymer.

Alpha, beta-unsaturated carbonyl modified amino acid monomer and

This invention relates to a cleansing composition comprising a particulate hydrophilic polymer or copolymer or mixture thereof and methods for cleaning various articles including contact lenses using the composition disclosed herein.

Contact lens cleaning composition with polymeric beads

Low N-vinyl lactam content copolymers are cross-linked with resonance free di(alkene tertiary amine) cyclic compounds to obtain biomedical devices, including soft contact lenses, which have good oxygen permeability and mechanical properties.

Low N-vinyl lactam content based biomedical devices

N-vinyl lactam monomers and comonomers are cross-linked with resonance free di(alkene tertiary amine) cyclic compounds to obtain biomedical devices, including contact lenses, which have high oxygen permeability and good mechanical properties.

N-Vinyl lactam based biomedical devices

Monomeric polysiloxanes end-capped with activated unsaturated groups polymerized with acrylic acid and a comonomer comprising a polycyclic ester of acrylic acid or methacrylic acid to form a hydrophilic, water absorbing contact lens is disclosed. These polysiloxane polymer contact lenses are unexpectedly capable upon hydration of retaining from 1 percent to about 99 percent by weight of water, based upon the total weight of the dry, i.e., unhydrated polymer.
