Abstract
Disclosed is a method of improving the release of paper webs from the surface of press rolls or other paper making or converting equipment by applying to such a surface non-aqueous, non-curing hydrocarbon polymer compositions. The non-curing hydrocarbon polymers have the formula (CH ) C—[—C(R )(R )—C(R )(R )—] —C(R )═C(CH ) (I) wherein R through R are hydrogen or —CH , with at least one of R through R being —CH , and n is such that the number average molecular weight of such hydrocarbon polymers is from 50 to 3000. They may be hydrogenated. Preferred non-curing hydrocarbon polymers are polybutenes of the formula (CH ) C—[—CH —C(CH ) —] —CH═C(CH ) (II). Preferred compositions comprise at least one such hydrocarbon polymer component having a number average molecular weight from 400 to 700 and a second such component having a number average molecular weight of 100 to 400. The compositions are applied to the equipment surface in the absence of water.
