A poly(2,6-dimethyl-1,4-phenylene ether) prepared using a morpholine-containing polymerization catalyst has a monomodal molecular weight distribution with a reduced content of very high molecular weight species. It also exhibits increased morpholine incorporation in the high molecular weight fraction. Compared to commercially available poly(2,6-dimethyl-1,4-phenylene ether) prepared using a di-n-butylamine-containing polymerization catalyst, the poly(2,6-dimethyl-1,4-phenylene ether) of the invention exhibits reduced odor. Compared to other poly(2,6-dimethyl-1,4-phenylene ether) prepared using a morpholine-containing polymerization catalyst, the poly(2,6-dimethyl-1,4-phenylene ether) of the invention exhibits improved molecular weight build during compounding and improved compatibilization with polyamides.

The use of an N,N-dimethyl alkylamide or an N-alkanoyl morpholine provides a stable emulsifiable concentrate composition that hinders de-esterification and transesterification of mixtures of a carboxylic acid herbicide and an ester of a different carboxylic acid herbicide. The N,N-dimethyl alkylamide or N-alkanoyl morpholine additionally stabilizes emulsifiable concentrates containing a triazolopyrimidine herbicide having at least one methoxy group on the triazolopyrimidine ring.

The invention relates to a hyper-branched polycarboxylate high-efficiency water reducing agent and a preparation method thereof. The water reducing agent is prepared by polymerizing one of tert-butyl acrylate and methyl tert-butyl acrylate with sodium methyl-acryl sulfonate and allyl polyethenoxy ether to form a copolymer main chain, and then performing condensation polymerization on one of acrylic acid and methacrylic acid with ethylene diamine to form a hyper-branched polyamide structure which is grafted to two ends of the main chain. The preparation method comprises the following steps: (1) preparing the sodium methyl-acryl sulfonate into solution with DMF, and heating the solution in a nitrogen atmosphere; (2) dissolving the other two monomers and an initiating agent into the DMF to prepare mixed solution, and dripping the mixed solution into the step (1) to react for 1 to 20 hours; (3) adding a condensating agent CDI after the reaction and performing condensation reaction by using N-methyl morpholine as an organic base, the ethylene diamine and the acrylic acid as the monomers and the DMF as a solvent; and (4) performing vacuum distillation to remove the residual monomers and the solvent, and refluxing for 2 to 5 hours by using methylene chloride solution of trifluoroacetic acid to obtain the water reducing agent. The hyper-branched polycarboxylate water reducing agent has the advantages of low admixture, high water reducing rate, small slump loss, good compatibility with cement, no corrosivity to steel bars, strong frost resistance and the like.
