Abstract:
Compositions are provided comprising a propylene-ethylene copolymer containing about 1 to about 7 weight percent ethylene and an ehtylene-alkyl acrylate copolymer containing at least about 20 weight percent ethylene, wherein the composition contains about 10 to 25 weight percent alkyl acrylate, based on the combined weight of propylene-ethylene copolymer and ethylene-alkyl acrylate copolymer. Films made from these compositions have good RF sealing properties, as well as good flexibility at low temperatures.
Abstract:
Disclosed are copolymers of ethylene and alkyl acrylate monomers and methods of making those copolymers. Said copolymers exhibit increased melt-point temperatures and decreased hardness over similar conventional copolymers, as well as improved optical properties.
Abstract:
Copolymères d'éthylène et de monomères d'acrylate d'alkyle et procédés de production de ces copolymères. Ces derniers présentent, par rapport aux copolymères classiques similaires, des températures de point de fusion plus élevées et une diminution de la dureté, de même que de meilleures propriétés optiques.
