摘要： PURPOSE:To obtain titled beads capable of giving highly-expanded products, by dispersing polyolefin resin beads in water within a closed vessel, adding volatile expanding agent, heating to specific temperature followed by sealing in the vessel a pressurized inorganic gas, then discharging the content into a lower-pressure atmosphere. CONSTITUTION:Polyolefin resin beads 2 are fed to a closed vessel 1, being dispersed in water 3, followed by charging the vessel 1 with a volatile expanding agent 6 and heating the resultant dispersion to a temperature higher than the softening point but lower than the melting point of said beads. Next, for maintaining the pressure in the vessel >=5kg/cm G at the discharge of the final portion 7 of said dispersion 3 containing the resultant beads 2, a pressurized inorganic gas 9 is sealed in the vessel prior to the discharge of the dispersion 3 followed by opening the delivery exit 7 provided under the water surface within the vessel, discharging said dispersion 3 into the atmosphere with a pressure lower than that in the vessel, thus obtaining the objective beads.

摘要： PURPOSE: A modified ethylene polymer good in moldability, adhesive property, and blendability, prepared by graft-modifying a specified ethylene polymer with vinyl acetate and having a specified vinyl acetate content and a xylene-insoluble portion.
CONSTITUTION: A modified ethylene polymer prepared by subjecting an ethylene polymer of a crystallinity of 4W50% and vinyl acetate to a graft reaction and having a vinyl acetate content (including vinyl acetate initially contained, if any) of 5W70wt% and a boiling xylene-insoluble portion of below 1wt%. An ethylene polymer having a crystallinity exceeding 50% is not desirable as the above ethylene polymer because the diffusion of vinyl acetate is difficult during impregnation, and it is difficult to obtain a uniformly graft-modified polymer, whereas an ethylene polymer having a crystallinity of below 4% has poor moldability and so is undesirable.

摘要翻译：目的：通过用乙酸乙烯酯接枝改性指定的乙烯聚合物并具有特定的乙酸乙烯酯含量和二甲苯不溶部分制备的具有良好成型性，粘合性和共混性的改性乙烯聚合物。构成：通过将结晶度为4-50％的乙烯聚合物和乙酸乙烯酯经受接枝反应并且具有5-70wt％的乙酸乙烯酯含量（包括最初含有乙酸乙烯酯（如果有的话））而制备的改性乙烯聚合物和沸点二甲苯不溶部分低于1重量％。结晶度超过50％的乙烯聚合物作为上述乙烯聚合物是不希望的，因为在浸渍过程中乙酸乙烯酯的扩散困难，难以获得均匀的接枝改性聚合物，而结晶度低于乙烯聚合物 4％的成型性差，所以不理想。

摘要： PURPOSE: To obtain the titled polymer useful as expandable polymer beads, etc., having a narrow particle size dstribution, by subjecting a monomer, e.g., styrene, etc. to bulk polymerization to a specific viscosity, feeding the polymer to water, followed by adding a specified amount of a monomer having no polymerization initator, and carrying out suspension polymerization.
CONSTITUTION: First, polymerizable ethylenic unsaturated monomers consisting essentially of styrene is subjected to bulk polymerization in the presence of a polymerization initiator until a viscosity of the reaction system at 20°C becomes 100W 10,000 centipoise to give a bulky styrene (co)polymer, which is fed to water containing a suspension stabilizer. 200W900pts.wt. polymerizable ethylenic unsaturated monomers consisting essentially of styrene containing no polymerization initiator based on 100pts.wt. monomer subjected to bulk polymerization is added to the reaction system and subjected to suspension polymerization. The polymerizationinitiator for suspension polymerization is added to the reaction system before the bulk polymer is fed to the suspension polymerization system.
