| 摘要 |
Aqueous polymer dispersions (I) obtained by polymerisation of chloroprene at 0-70degreesC, optionally with unsaturated comonomers, in which the gel content (based on polymer) is increased by at least 10% to 1-60 wt% (from an original value of 0.1-30 wt%) by storage at 50-110degreesC. Independent claims are also included for (1) adhesive formulations containing these aqueous dispersions (2) substrates coated with these formulations. |
