Abstract
The present invention pertains to a curable composition comprising (a) at least one ethylene polymer, (b) less than 2 parts by weight of at least one monoperoxycarbonate for 100 parts by weight of constituent (a), (c) from 0.4 to less than 4 part by weight of at least one t-alkyl hydroperoxide for 100 parts by weight of constituent (b). It is also directed to a method for preventing scorching of a curable composition comprising an ethylene polymer, by adding a specific amount of t-alkyl hydroperoxide thereto and to a method for manufacturing a scorch-protected material.
Claims16
A curable composition comprising:
- (a) at least one ethylene polymer,
- (b) less than 2 parts by weight of at least one monoperoxycarbonate for 100 parts by weight of constituent (a),
- (c) from 0.4 to less than 4 parts by weight of at least one t-alkyl hydroperoxide for 100 parts by weight of constituent (b).
(canceled)
A method for preventing scorching of a curable composition comprising (a) at least one ethylene polymer, and (b) at least one monoperoxycarbonate, comprising the step of adding at least one t-alkyl hydroperoxide into the composition, in an amount of from 0.4 to less than 4 parts by weight for 100 parts by weight of constituent (b).
A method for manufacturing a scorch-protected material comprising an ethylene polymer, said method comprising a step a) of curing a composition comprising:
- (a) at least one ethylene polymer,
- (b) less than 2 parts by weight of at least one monoperoxycarbonate for 100 parts by weight of constituent (a), and
- (c) from 0.4 to less than 4 parts by weight of at least one t-alkyl hydroperoxide for 100 parts by weight of constituent (b).
