    摘要: There is disclosed a process for the production of polymeric polyols, which comprises the steps of:partially or completely saponifying a heterogeous two-phase mixture of (a) a heated molten liquid containing an ethylene-saturated carboxylic acid vinyl ester copolymer having a number average molecular weight of from 800 to 5000 and a saturated carboxylic acid vinyl ester content of from 1 to 50% by weight, and (b) an aliphatic alcohol, in the presence of an alkali catalyst, while removing a saturated carboxylic acid alkyl ester byproduct from the reaction system;then removing the residual aliphatic alcohol from the reaction system; andsupplying an alkylene oxide to effect an alkylene oxide-addition reaction, optionally after further supplying the alkali catalyst.

    摘要: An adhesive resin composition is obtained by mixing at least one member (C) selected from the group consisting of unsaturated carboxylic acids and the derivatives thereof, a free-radical initiator (D), and a mixture consisting of a crystalline polyolefin resin (A) and an amorphous or low crystalline olefin copolymer of ethylene and an .alpha.-olefin (B), to obtain a precursor mixture, melt-kneading the precursor mixture in the first half of an extruder having at least one side feeder, to obtain a modified precursor mixture, and feeding a crystalline polyolefin resin (E) from the side feeder of the extruder and mixing the resin (E) with the modified precursor mixture.The adhesive resin composition has good extrudability and exhibits high adhesive property to polar materials such as polar polymeric materials and the like.
