The invention provides a binder resin and a primer composition, paint composition, ink composition an adhesive composition with excellent gasohol resistance, adherence, weather resistance, etc. to polyolefinic resins and relates to a binder resin for polyolefinic resins comprising carboxyl group-containing chlorinated polyolefin (II), which contains not more than 2% of a component with molecular weight of 2,000 or lower and which has a ratio of weight average molecular weight (Mw) to number average molecular weight (Mn), that is the value Mw/Mn of not more than 4.
摘要:
The invention provides a novel binder resin composition. A binder resin composition characterized by comprising carboxyl group-containing chlorinated syndiotactic polyolefin resin with chlorine content of 0.1 to 40 wt. %, grafting level of &agr;,&bgr;-unsaturated carboxylic acid and/or its acid anhydride of 10 wt. % and weight average molecular weight of 30000 to 220000 and organic solvent. The carboxyl group-containing chlorinated syndiotactic polyolefin obtainable from polyolefin resin produced using metallocene compound exhibits good state of solution even if the chlorine content may be low, and is excellent in the adherence to polyolefinic prime material and the solvent resistance.
摘要:
A binder resin containing a mixture of carboxyl group containing chlorinated polyolefins and an ethylene-vinyl acetate copolymer. The binder resin is incorporated in primer formulations for application on substrates including polyolefinic materials.
摘要:
Disclosed is a chlorinated polyolefin composition with good stability with 0.1 to 10 parts by weight of hydrotalcites compound and 1 to 10 parts by weight of epoxy compound with epoxide equivalent of 100 to 500 added to 100 parts by weight of chlorinated polyolefin with chlorine content of 5 to 50% by weight, hydrotalcite compound/epoxy compound being within a range of 0.01 to 10 (weight ratio). The subject is to provide a chlorinated polyolefin composition and producing method thereof for paints, primers, printing inks or adhesives with more improved adherence and other physical properties to polyolefin by improving the stability of chlorinated polyolefin.

摘要:
A method and an apparatus for winding a cord continuously. A rotation of a winding bobbin around which a cord to be a tension member of a belt and so on is wound is detected directly or indirectly. A cord is forwarded in an axial direction of a winding bobbin at a pitch, which corresponds to a diameter of the cord, in relation to a rotation of a winding bobbin. And a bobbin axis of the winding bobbin is rotated at a constant speed by rotation driving means so that the cord is wound around the winding bobbin. The rotation of the bobbin axis is detected by rotation detection means directly or indirectly. The cord is forwarded in the axial direction of the winding bobbin in relation to the rotation of the winding bobbin at a pitch which corresponds to the diameter of the cord by receiving signals from the rotation detection means.
