Title:
改良された耐熱性を有するエチレンアルキルアクリレートコポリマー
Document Type and Number:
Japanese Patent JP2004527595
Kind Code:
A
Abstract:
The invention provides a copolymer of ethylene and at least 5 mol % of comonomer units derived from an alkyl acrylate or alkyl methacrylate, wherein the copolymer has a melt index of from 1 to 10,000 g/10 min, and a maximum peak melting temperature of at least 100 DEG C. The alkyl group of the alkyl acrylate or alkyl methacrylate can e a linear or branched C1 to C12 group, particularly n-butyl. The copolymer shows increased heat resistance as characterized by a temperature required to melt 50 % of the copolymer of at least 80 DEG C, a temperature required to melt 80 % of the copolymer of at least 100 DEG C, a temperature required to melt 100 % of the copolymer of at least 110 DEG C. The invention further provides a process for copolymerizing ethylene and an alkyl acrylate or alkyl methacrylate comonomer.
