Abstract
Abstract Thermoplastic, soluble ethylene-carbon monoxide copolymers are produced using a Pd(CN) 2 catalyst in the presence of an alkanoic acid substituted by a halide group on an alpha carbon. The polymers are useful for forming films and fibers and can be incorporated in the thermoplastic, coating or adhesive compositions, e.g., in hot melts, to improve the adhesion and consistency of films prepared therefrom.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
116 words
The process of producing a high melting point, thermoplastic telomer of ethylene and carbon monoxide having a number of repeating monomeric units within the range of 2 to about 30, which process comprises reacting ethylene and carbon monoxide in a liquid medium containing an alkanoic acid having from 2 to about 6 carbons and bearing at least one halo group on an alpha carbon under reaction conditions including a temperature of about 50° to about 205° C. and a pressure of about 1 to about 200 atmospheres, in the presence of palladium cyanide, the initial ratio of ethylene to carbon monoxide being about 1/5 to about 5/1, sufficient to produce said high melting point, thermoplastic telomer.
Claim 2
Dependent Claim
116 words
The process of producing a high melting point, thermoplastic telomer of ethylene and carbon monoxide having a number of repeating monomeric units within the range of 2 to about 30, which process comprises reacting ethylene and carbon monoxide in a liquid medium containing an alkanoic acid having from 2 to about 6 carbons and bearing at least one halo group on an alpha carbon under reaction conditions including a temperature of about 50° to about 205° C. and a pressure of about 1 to about 200 atmospheres, in the presence of palladium cyanide, the initial ratio of ethylene to carbon monoxide being about 1/5 to about 5/1, sufficient to produce said high melting point, thermoplastic telomer.
