Abstract:
The present application relates to a method for manufacturing a propylene polymer, including: a) fermenting and optionally purifying first renewable materials to produce an alcohol or an alcohol mixture, the alcohol or alcohol mixture including at least isopropanol and/or at least a mixture of ethanol and 1-butanol; b) dehydrating the resulting alcohol or the alcohol mixture to produce an alkene or alkene mixture in a first series of reactors, the alkene or alkene mixture containing at least propylene; c) polymerizing the propylene in a second reactor, optionally in the presence of a comonomer, so as to produce a propylene polymer; d) isolating the propylene polymer obtained in step c); and e) grafting the propylene polymer obtained from step d). The invention also relates to the grafted propylene polymer capable of being obtained by the method, to the compositions containing the polymer, as well as to the uses of the polymer.
Abstract:
A polyolefin wax-containing aqueous resin composition that can provide excellent properties without the use of a surfactant is provided. The aqueous resin composition is obtained by heating and dissolving 100 parts by mass of a carboxyl group-containing polyolefin wax in the presence of 15 to 67 parts by mass of a compound that satisfies general formula (1) shown below, and 90 to 380 parts by mass of water, and then dispersing this with a basic compound that has been added at a ratio of 1 to 4 chemical equivalents per carboxyl group of the carboxyl group-containing polyolefin wax. €ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒGeneral Formula (1) C m H 2m+1 -(OCH 2 CH 2 ) n -OH m: an integer from 4 to 6, n: an integer from 1 to 4
Abstract:
PROBLEM TO BE SOLVED: To provide an anticorrosive polyamide resin composition endowed with outstanding corrosion resistance by virtue of outstanding elongation and strength of adhesion to polyolefin resins and metals.SOLUTION: The polyamide resin composition contains a resin component comprising 70-90 mass% of a polyamide resin and 10-30 mass% of an acid-modified polyolefin resin. The acid-modified polyolefin resin is preferably a maleic-anhydride-modified polyolefin resin. The polyolefin resin is preferably polypropylene.
