摘要：
A modified polyolefin resin obtained by melt-kneading a mixture consisting of
100 parts by weight of a mixture consisting of
(A) 40-99% by weight of a polyolefin resin having a melt flow rate of 0.05-60 g/10 min and (B) 60-1% by weight of a solid rubber having a number-average molecular weight of 10,000-200,000, (C) 0.1-5 parts by weight of at least one compound selected from the group consisting of unsaturated carboxylic acids, the derivatives thereof and unsaturated epoxy compounds, (D) 0.1-5 parts by weight of an unsaturated aromatic compound and (E) 0.01-2 parts by weight of a free-radical initiator,
the molar ratio of (C)/(D) ranging from 1/0.1 inclusive to 1/1 exclusive. According to the present invention, there is provided a modified polyolefin resin having the following merits:
(1) The amount of bound unsaturated carboxylic acid, a derivative thereof or unsaturated epoxy compound is high. (2) The change of the melt flow rate during the modification is small. (3) The physical properties are of high grade. (4) The coating affinity with urethane coatings and resistance to falling off of the coating layer are excellent. The modified polyolefin resin of the present invention can be used for adhesives, covering materials, binders, laminate bonding agent and polymer alloy constituents.
