Abstract: In a process for producing a molecular sieve material, water, at least one source of an oxide of a tetravalent and/or a trivalent element and at least one structure directing agent is mixed in a reactor equipped with a mixer having a Froude number of at least 1, to produce a molecular sieve synthesis mixture having a solids content of at least about 20 wt %. The molecular sieve synthesis mixture is heated in the reactor while agitating the mixture with said mixer to form crystals of said molecular sieve material and the molecular sieve crystals are subsequently recovered from the reactor.

Abstract: A hydrocarbon polymer modifier (HPM) having high softening point and high aromaticity, is an interpolymer of (i) a piperylene component; (ii) an aromatic component; and (iii) a cyclic pentadiene component comprising a dicyclopentadiene fraction (DCPD fraction) and a dimethylcyclopentadiene fraction (MCPD fraction), wherein a weight ratio of the MCPD fraction to the DCPD fraction is from 0.8 to 20, and wherein the MCPD fraction is at least 20 wt % of the cyclic pentadiene component. In a method, the proportions of (i), (ii), (iii), and an optional amylene component are adjusted to control aromaticity, softening point and Mz of the HPM. An elastomeric composition incorporates the HPM.
