The amidation reaction is of a very particular interest, especially in the pharmaceutical industry and always requires the activation of the acid with a large excess of reactants. Therefore, a large amount of waste is generated. In order to reduce the environmental impact of such reaction, we have developed enzymatic amidation conditions which are compatible with a wide range of amines and acids, in
The object of the present invention is to provide a polyethylene resin composition which is improved in anti-blocking and slipping properties, and further in antistatic properties without deteriorating the excellent properties of polyethylene, such as transparency and heat sealability.
The inventive polyethylene resin composition comprises
(A) polyethylene,
(B) a zeolite or an anhydrous amorphous aluminosilicate having the basic particle characteristics of zeolite as prepared by acid-treating zeolite,
(C) fatty acid amide having a melting point of not more than 130 °C, and
(D) an antistatic agent.
