Abstract
A polymer obtainable by reacting a compound A) comprising at least one five-membered cyclic monothiocarbonate group and at least one polymerizable, ethylenically unsaturated group, a compound B) comprising at least one amino group, selected from primary or secondary amino groups, optionally a compound C) which is different from compound A) and comprises at least one five-membered cyclic monothiocarbonate group, and optionally a compound D) which is different from compound A) and comprises at least one functional group that reacts with a group —SH.
Claims20
A polymer, obtained by reacting:
- a compound A) comprising one to three five-membered cyclic monothiocarbonate groups and at least one polymerizable, ethylenically unsaturated group,
- a compound B) comprising at least one amino group, selected from the group consisting of primary and secondary amino groups,
- optionally, a compound C) which is different from compound A) and comprises at least one five-membered cyclic monothiocarbonate group, and
- optionally, a compound D) which is different from compound A) and comprises at least one functional group that reacts with a group —SH wherein the five-membered cyclic monothiocarbonate group of compound A) is opened by the reaction with the amino groups of compound B) to form an adduct comprising a SH group and a polymerizable, ethylenically unsaturated group, followed by a reaction of the SH group with the polymerizable, ethylenically unsaturated group.
A two component curable system, consisting of:
- a first component comprising a compound A) comprising one to three five-membered cyclic monothiocarbonate groups and at least one polymerizable, ethylenically unsaturated group,
- optionally, a compound C) which is different from compound A) and comprises at least one five-membered cyclic monothiocarbonate group, and
- optionally, a compound D) which is different from compound A) and comprises at least one functional group that reacts with a group —SH, and
- a second component comprising a compound B) comprising at least one amino group, selected from the group consisting of primary and secondary amino groups wherein when compound A) and compound B) are combined, the five-membered cyclic monothiocarbonate group of compound A) is opened by the reaction with the amino groups of compound B) to form an adduct comprising a SH group and a polymerizable, ethylenically unsaturated group, followed by a reaction of the SH group with the polymerizable, ethylenically unsaturated group.
A process for the manufacturing of a polymer, the process comprising:
- reacting
- a compound A) comprising one to three five-membered cyclic monothiocarbonate groups and at least one polymerizable, ethylenically unsaturated group,
- a compound B) comprising at least one amino group, selected from the group consisting of primary and secondary amino groups,
- optionally, a compound C) which is different from compound A) and comprises at least one five-membered cyclic monothiocarbonate group, and
- optionally, a compound D) which is different from compound A) and comprises at least one functional group that reacts with a group —SH,
- wherein compound B) is used in an amount to transfer at least 10 mol % of the monothiocarbonate groups of compounds A) and optionally C) into —SH group, and wherein the five-membered cyclic monothiocarbonate group of compound A) is opened by the reaction with the amino groups of compound B) to form an adduct comprising a SH group and a polymerizable, ethylenically unsaturated group, followed by a reaction of the SH group with the polymerizable, ethylenically unsaturated group.
