Abstract
PURPOSE: Title composition that is made by heating a mixture of an elastomer as ethylene-propylene compolymer elastomer and a low-molecular and amorphous polyolefin in the presence of an aorganic peroxide, thus having high elasticity and low melt viscosity.
CONSTITUTION: (A) 100 parts by wt of a polymer blend resulting from melt blending at least one of elastomer selected from ethylene-propylene compolymer elastomer, polyisobutylene and butyl rubber and an amorphous polyolefin of relatively low molecular weight are mixed with (B) 0.3W3 parts of an organic peroxide and kneaded at 150W200°C for 10W20min to give said composition substantially containing no gel or insoluble product.
EFFECT: Even when a relatively large amount of elastomer is added, the melt viscosity does not exceed the practical range.
USE: Said composition is combined with a tackifier to give hot-melt adhesive and sealant.
