摘要:
The invention relates to low molecular weight, liquid EP(D)M compositions suitable for coatings, especially roof coatings, flashings, caulks, and sealants, the composition comprising a copolymer of ethylene and a monomer having the formula CH 2 CHR wherein R is C 1 -C 10 linear or branched alkyl, said copolymer having a molecular weight of 500-20,000, the composition also including a reinforcing agent, a curative for the copolymer and no more than a minor amount of solvent. Methods of making waterproof membranes, including the composition, are also described.
摘要:
Manufacture articles in the form of sheets coated with a composition consisting of: a) from 75 to 99 parts by weight of a polypropylenic material of melt index comprised between 5 and 60, consisting of a prevailingly isotactic polymer of propylene; b) from 1 to 25 parts b.w. of polyethylene having a density comprising between 0.910 and 0.935, having a melt index comprised between 1 and 10, or of an ethylene-propylene copolymer of the amorphous type, having a melt index comprised between 1 and 50; c) from 0.01 to 0.2 parts b.w. on 100 parts of polymeric composition of an organic sulphide of formula: A-S-B wherein A and B, equal to or different from each other, are aryl, alkyl, alkylaryl groups, at least one of the groups A and B being an aryl containing a functional hydroxyl group in position 2 or 4 with respect to S, and at least one linear or branched alkyl group.
