Process for producing hydroxylated plasma-polymerized films and the use of the films for enhancing the compatiblity of biomedical implants

A blow molded multilayered container comprises a layer of a polyalcohol obtained by reduction of a polyketone comprising carbon monoxide-ethylene copolymer and a layer of a thermoplastic resin other than polyalcohol, said polyalcohol having an intrinsic viscosity of 0.3 to 3.0 dl/g, a melting point of 110° to 160° C., a density of 1.12 to 1.21 g/cm 3 and a tetrahydrofuran ring content of not more than 10 mole %.

Blow molded polyalcohol container

Selectively hydrogenated block polymers of an alkenyl aromatic compound and a conjugated alkadiene are functionalized by the presence of a plurality of carbamoyl substituents on aromatic rings in the aromatic portion of the polymer. Such carbamoyl-functionalized derivatives are produced by reaction of corresponding carboxylic acid-functionalized polymers by reaction with ammonia followed by application of heat. The carbamoyl-substituted polymers exhibit improved properties and form blends with engineering thermoplastics.

Process of producing functionalized elastomeric polymers

This invention relates to a process of reducing polyketones to polyalcohols using borohydride salts where the reducing agent is suspended in water.

Reduction of α-olefin-carbon monoxide copolymers to polyalcohols with borohydride salt

A functionalized polyketone and a method to make this functionalized polyketone is provided, the method including the steps of: providing a polyketone; contacting the polyketone with a functional group containing monomer, the functional group containing monomer having a double bond between two carbons, at a temperature between about 180° C. and 275° C., for a time period effective for at least 10% by weight of the resultant grafted polymer to be grafted monomer units; and recovering the grafted polyketone.

Water soluble polyketones

A polymeric polyalcohol of high molecular purity is obtained by sodium botohydride reduction of a linear alternating copolymer of carbon monoxide and ethylene in a liquid-phase solution in hexafluoroisopropanol at ambient temperature and pressure.
