摘要:
This invention concerns a composition comprising a blend of polyolefin with the reaction of a functionalized polyolefin and polyetheramine in which the polyetheramine is grafted into the functionalized polyolefin in a customary mixing apparatus. A process for producing the reaction product of functionalized polypropylene and polyetheramine by melting with polypropylene in a customary mixing apparatus is also disclosed. Blends of the present invention are advantageously useful to prepare paintable automotive body parts. This invention further includes dyeable polyolefin compositions containing the reaction product of functionalized polyolefin and polyetheramine. Dyeable polyolefin fibers, including polypropylene fibers, are disclosed, which may be made by melt spinning, and which may be employed to make woven and non-woven fabric. The polyolefin employed in the practice of this invention may be a flexible polyolefin.

摘要:
The unitary cylinder liner incorporating a water jacket is vertically cast as a one piece unit. The water jacket is draftless, allowing water to circulate therethrough more efficiently, increasing cooling capabilities. Such vertical one piece casting is made possible by the novel two piece core which eliminates the need for welding of metal bands onto an outer surface of the liner to produce the water jacker thereof. A novel method of vertical casting is also provided by use of the two piece core.
