摘要

The present invention is a method for increasing the melt strength of a polyethylene resin comprising reacting the polyethylene resin with an alkoxy amine derivative corresponding to the formula: (R1)(R2)N-O-R3 where R1 and R2 are each independently of one another, hydrogen, C4-C42 alkyl or C4-C42 aryl or substituted hydrocarbon groups comprising O and/or N, and where R1 and R2 may form a ring structure together; and where R3 is hydrogen, a hyrdrocarbon or a substituted hydrocarbon group comprising O and/or N. Preferred groups for R3 include -C1-C19alkyl; -C6-C10aryl; -C2-C19akenyl; -O-C1-C19alkyl; -O-C6-C10aryl; -NH-C1-C19alkyl; -NH-C6-C10aryl; -N-(C1-C19alkyl)2. R3 most preferably contains an acyl group.
