摘要:
Fabrics, particularly cellulosic fabrics is resin finished with a combination of 1,3-dimethylglyoxalmonourein and trimethylolpropane, whereby the fabrics has improved crease resistance and shrink-proofing and generates no unpleasant odor.
摘要:
An epoxy resin composition comprising a polyglycidyl ether prepared by reacting a 3-methyl-6-alkylphenol in the presence or absence of a phenol other than the 3-methyl-6-alkylphenol with an aldehyde to obtain a novolak, and then reacting the novolak with an epihalohydrin, which composition is useful in electronic fields, for example, for encapsulating semiconductor products or for the production of printed circuit boards.

摘要:
A thermosetting resin is prepared by mixing or reacting (a) an alkylene diamine or polyalkylenepolyamine with (b) an epihalohydrin (preferabiy chiorohydrin), and (Y) a watersoluble resin obtained by reacting
(i) urea, (ii) a polyalkylenepolyamine, and (iii) a dibasic carboxylic acid (e.g. adipic)
and reacting the resultant polyamidopolyurea (PAPU) formaldehyde. The PAPU can be made by reacting (i) + (ii) and the product with (iii), or (ii) + (iii) and the product with (i), at specified reaction conditions. (Y), (a) and (b) may all be reacted or mixed together, or first (Y) and (b) and then (a), or (a) and (b) then (Y). The thermosetting resin is mixed into a paper coating composition including a conventional pigment, binder and water, and the composition is coated onto paper and dried to make a coated paper which has good waterresistance (due to the resin (Y)) whilst being receptive to rotary offset printing ink. ,
摘要:
An aqueous solution of a cationic thermosetting resin containing a very small amount of organic halogen compounds is prepared by adjusting a reaction temperature in a reaction of polyamidopolyamine with epihalohydrin and a molar ratio of the polyamidopolyamine and epihalohydrin.
摘要:
An epoxy resin composition comprising (A) an epoxy resin having three or more epoxy groups per molecule and (B) an reactive oligomer having in its molecule an aromatic residue connected thereto by an -0- or -S- linkage and having at the terminal of the molecule a phonolic hydroxyl group.
摘要:
A thermosetting resin composition comprising an N,N'- bismaleimide compound and an allylated phenol novolak resin having partially or wholly allyl-etherified phenolic hydroxyl groups and substantially no nucleous-substituted allyl group.
