(WO201692785) This treatment liquid for shaped metallic materials includes at least 40% by mass of an acid-modified polypropylene relative to the total resin content thereof. The melt viscosity of the non-volatile component of the treatment liquid for shaped metallic materials is 1,000-10,000 mPa·s.
(WO201693678) The present invention relates to a novel supported metallocene catalyst and a polyolefin preparation method using the same. The supported metallocene catalyst according to the present invention can be used for preparing polyolefins, has excellent activity and reactivity with a comonomer, and can effectively prepare olefinic polymers of high molecular weight and low molecular weight.
(WO201692274) A method of preparing a foamed thermoplastic polymer comprises contacting a chemical blowing agent (A) which is a semi-carbazide with a thermoplastic polymer or a precursor of a thermoplastic polymer. Blowing agent (A) is preferably p-toluenesulfonyl semi-carbazide and said polymer is preferably PVC. Formulations, including liquid formulations which include the blowing agent (A) and other ingredients, are also described.
