Formula selection for the use of modified hydroxyl alkyl amide in pure polyester powder system;

Synthesis and characterization of a novel curing agent β-hydroxyalkylamide

The curing agents ofβ-hydroxyalkylamides are widely used in polyesters which contain carboxyl and anhydride groups because of their non toxicity,high efficiency,economy and ecology.

In the text, a series of hydroxyalkylformamides (HAF) were synthesized from alcohol amine and ethyl formate without solvent and catalyst.

By double decomposition and alkaline polymerization,amino and stearamoyl modified polysiloxane were prepared with stearamid,γ-chloropropyl,methyl,diethoxyl silane,octamethyl cyclobutasiloxane and N-β-aminoethyl-γ-aminoprpyl,methyl,and dimethoxyl silane as raw material.

In order to develop a silicone modified polyurethane latex for leather, a series of alkylhydroxyl-containing silicone with active hydrogen was synthesized, characterized, and used to prepare the alkylhydroxyl-containing silicone modified polyurethane latex;the performance of alkylhydroxyl-containing silicone modified waterbome polyurethane on leather surface was investigated.
