- 10. The product of claim 9 wherein the copolymerizable olefinically-unsaturated comonomer comprises acrylic acid or methacrylic acid.
- 11. The product of claim 9 wherein the copolymerizable olefinically-unsaturated comonomer is acrylic acid.
- 12. The product of claim 9 wherein the copolymerizable olefinically-unsaturated comonomer is methacrylic acid.
- 13. The product of claim 9 wherein the modifier comprises one or more alkanes.
- 14. The product of claim 9 wherein the modifier comprises an alcohol.
- 15. The product of claim 9 wherein the modifier is isobutane.
- 16. The product of claim 9 wherein the modifier is methanol.
- 17. A random, homogeneous, single-phase interpolymer product having a melt flow rate in the range of about 0.1 to about 300 g/10 minutes, as determined by ASTM D-1238 (190.degree. C./2160 g), comprising about 65% to about 99% by weight of ethylene monomer, the remaining percentage comprising (a) at least one olefinically-unsaturated comonomer selected from the group consisting of unsaturated carboxylic acids, and (b) a minor amount of telogenic modifier said interpolymer being further characterized as having product improvements over those achievable without the presence of said telogenic modifier, which is at least one selected from the group consisting of alkanes, alkenes, alcohols, ketones, hydrogen, silanes, cyclic hydrocarbons, aromatic hydrocarbons, halogenated hydrocarbons, sulfoxides, ethers, esters, amines, amides, nitriles, anhydrides, furans, aldehydes, cyanates, or sulfides, at concentrations from about 0.0001 weight % to about 10 weight %, said product improvements being further characterized by the product having less long chain branching, and wherein said interpolymer product has a gel rating less than 2.
