Abstract: Particle mixts. contg. 20-200 penetration bitumen 100, ethylene polymer 1-200 and optionally up to 50 pts. by wt. of polyisobutylene are prevented from agglomerating or caking by treatment with an aq. dispersion contng. (a) 20-50 wt.% of finely divided polymer consisting of at least 60 wt.% of vinyl- or vinylidenechloride polymer units. (b) 4-20 wt.% to finely divided melamine, melamine- and/or urea-CH2O resin, such that the sum of the wt.% in (a) and (b) is less than 60. The product is then dried.
