【発明の名称】エチレンのターポリマー、その製法および鉱油留分の添加物としてのそれの用途
Document Type and Number:
Japanese Patent JP2925078
Kind Code:
B2
Abstract:
Terpolymers (I) of ethylene with 10-35 wt.% vinyl ester of a 2-20C aliphatic monocarboxylic acid and 0.5-20 wt.% 4-Me-pentene-1 (4-MP-1) have a 140 degrees C melt viscosity of 20-10,000mPa.s. Also claimed are: (a) the preparation of (I) by radically-initiated polymerisation of a mixture of ethylene, 5-40 wt.% of the vinyl ester and 1-40 wt.% 4-MP-1 at 50-350 degrees C/50-400 MPa optionally with a moderator; (b) (i) 20:1-1:20 wt. ratio mixtures of (I) with EVA copolymers or with ethylene/vinyl acetate/vinyl-neononanoate or-neodecanoate terpolymers or (ii) 1:10-20:1 wt. ratio mixtures of (I) with paraffin dispersants or with comb polymers; and (c) mineral oils or distillates containing 0.0005-1 wt.% of (I) or their mixtures as in (b).
