摘要:
Impact modified compositions having good impact performance can be made from a thermoplastic (e.g., a polyolefin such as polypropylene or HDPE) and a multi-block ethylene/α-olefin interpolymer. The compositions are easily molded and often have particular utility in making, for example, automotive facia, parts and other household articles.

The present invention is concerned with curable adhesive compositions for anchoring elements in a structural body that exhibit low temperature versus standard temperature degree of cures that are at least 50% or higher. The compositions include, in a first component, a reactive resin, an acetoacetoxy functional monomer and a silane monomer. By using phthalate-free constituents in the formulation, a further 10% increase in strength and durability of the resins at standard temperatures may be realized after curing at low temperatures.
