Abstract
A process for preparing low melting copolymers comprising contacting a mixture of olefin monomers with a CpFlu-type metallocene catalyst under reaction conditions sufficient to form a copolymer. The copolymers thus prepared desirably display melt temperatures from about 100° C. to about 140° C. and may be produced with reduced amounts of ethylene. The copolymers may also exhibit reduced levels of undesirable xylene solubles, relatively narrow molecular weight distribution, and other improved optical and physical properties.
