Elemental sulfur is {produced|created|made|developed} as a by-product {of the|from the|in the|on the|with the|of your} refining {process|procedure|method|approach|course of action} {of the|from the|in the|on the|with the|of your} petrochemicals {industry|business|market|sector}. This generates an excess of sulfur {each|every|each and every|every single} year that {currently|presently|at present|at the moment} goes unused. A {process|procedure|method|approach|course of action} {known as|referred to as|called|generally known as} inverse vulcanization {allows|enables|permits|makes it possible for} polymeric mate-rials {to be|to become} formed from elemental sulfur, stabilised with organic comonomers or crosslinkers.
